"(Remember) the day when We will summon every people with their Imam (guide); then whosoever is given his book in his right hand, then these shall read their book (joyfully) and they shall not be dealt with unjustly". (17:71)

In explaining the above verse, the Holy Prophet Muhammad (saw) said, "(On that day) everyone will be summoned with the Imam of their time, Book of their Lord and the Sunnah (tradition) of their Prophet". (Namoona)

The foremost principle of Ali, Abu Turab (as)'s life was: Having firm belief and faith in Almighty Allah (SWT). Ali, Abu Turab (as) therefore based his entire life upon the teachings and guidance of Holy Quran. That's why Holy Prophet Muhammad (saw) said: "Ali is with Quran and Quran is with Ali".

Ali, Abu Turab (as) said, "Ask me (anything) about the Book of Allah (Holy Quran). By Allah! There is not a single verse which was revealed during night or day, during travel or at home, but the Holy Prophet Muhammad (saw) read it to me and taught me its meanings..." (Amali of Shaykh al-Toosi)

Ali, Abu Turab (as) also said, "If authority is given to me and I have to act as a judge, I will judge the followers of Tawrat from Tawrat, the followers of Injeel from Injeel, the followers of Zaboor from Zaboor and followers of Furqan (Quran) from Furqan. By Allah! There is not a single verse which has been revealed during night or day, in the field or in the mountains but that, I possess its knowledge as to where it was revealed and for whom it was revealed".

After the death of Holy Prophet Muhammad (saw), the Justice of Ali, Abu Turab (as) was very popular. Even the first three Caliphs resorted to him in numerous cases.

Holy Prophet Muhammad (saw) said: The foremost judge amongst you is Ali.

During the days of second Caliph Umar ibn al-Khattab, a woman was arrested and presented before him.

People said, "O Khalifa! This woman has committed adultery. She has delivered a child after only a period of six months pregnancy".

Umar ibn al-Khattab ordered the woman to be stoned to death.

As people were taking her towards the location for punishment, she kept on pleading that she was innocent but no one would listen to her.

Finally someone informed Ali, Abu Turab (as) about the situation and he (as) came to Umar ibn al-Khattab and asked, "Why have you ordered this woman to be stoned to death?"

Umar ibn al-Khattab replied, "For adultery! She has given birth to a child after a period of six month's pregnancy and we all know the pregnancy period is of nine months".

Ali, Abu Turab (as) said, "This is not true! It is possible for a woman to give birth after six months pregnancy. This child belongs to her husband".

When asked for Quranic evidence, Ali, Abu Turab (as) said, "Allah (SWT) says at one place: "And the mothers should suckle their children for two years" (2:233) and in another place Allah (SWT) says: "And the bearing of him and the weaning of him is thirty months" (46:15) If the period of weaning which is two years (24 months) is subtracted from thirty months (which is overall period of bearing & weaning), there remains only six months. This proves that pregnancy period can be of six months.

So Umar ibn al-Khattab set the woman free and said, "If Ali had not been there, Umar would have perished."

A case was brought before Umar ibn al-Khattab, the second Caliph. Two babies, a girl and a boy, were born on a single dark night to two wives of the same man. The father of the babies had passed away and both wives claimed to be the mother of the son.

Umar ibn al-Khattab asked, "Where is Abul Hasan, vanquisher of difficulties?"

Ali, Abu Turab (as) was called for and the case detailed to him. He called for two small vessels to be brought and had them weighed and then instructed that equal amount of milk from each mother be drawn into a vessel.

When they were weighed again, it was found that one was heavier than the other. Ali, Abu Turab (as) declared that the mother with the heavier milk was the mother of the boy and the lighter milk was that of the girl's mother.

Umar ibn al-Khattab asked how he comes to this conclusion. Ali, Abu Turab (as) replied that Allah has prescribed that, "For a male is the share of two females."

Holy Prophet Muhammad (saw) said: "Whoever wishes to see Adam in his knowledge, Noah in his piety, Abraham in his forbearance, Moses in his strength, and Jesus in his worship and devotion should look at Ali ibn Abi Talib."

Holy Prophet Muhammad (saw) said the following about Ali ibn Abi Talib:

He is the first one to believe in Islam; He is the most knowledgeable; He is the most correct one in his DEEN; He is the most certain; He is the most patient; He is the most forgiving and generous; He is the bravest in heart; He is the IMAM and the successor after me.

Ali, Abu Turab (as) said: "By Allah, even if I am given all the domains of the seven (skies) with all that exists under the skies in order that I may disobey Allah to the extent of snatching one grain of barley from an Ant, I would not do it. For me, your world is lighter than the leaf in the mouth of a locust that is chewing it. What has Ali to do with bounties that will pass away and pleasures that will not last?"

At another place Ali, Abu Turab (as) said: "The world is a corpse. Whoever seeks it is a dog."

"O Ammar, grieve not if the pleasures of this world are kept away from you. Honey, the best and sweetest food, is the saliva of an insect, the bee. The nicest dress is made of silk which is the refuse of a small worm. The most refreshing scent, musk, is the blood of an animal, the deer. The best drink is water which is also used by animals to quench their thirst. The most passionate act is cohabiting in which urinative organs are used."

This world is like a serpent, so soft to touch, but so full of lethal poison. Unwise people are allured by it and drawn towards it, and wise men avoid it and keep away from its poisonous effects.

When this world favors anybody it lends him qualifications, and attributes surpassing merits of others, and when it turns its face away from him it snatches away even his own excellences and fame.

"I wonder at the mentality of a miser, fearing poverty he takes to stinginess and thus hastily pushes himself headlong into a state of want and destitution, he madly desires plenty and ease, but throws it away without understanding. In this world he, of his own free will, leads the life of a beggar and in the next world he will have to submit an account like the rich.

I wonder at the arrogance of a haughty and vain person. Yesterday he was only a drop of semen and tomorrow he will turn into a corpse.

I wonder at the man who observes the Universe created by Allah and doubts His Being and Existence.

I wonder at the man who sees people dying around him and yet he has forgotten his end.

I wonder at the man who has seen the first life (understands the marvel of genesis of creation) and denies the second life (refuses to accept that he will be brought back to life again).

I wonder at the man who takes great pains to decorate and to make comfortable this mortal habitat and totally forgets his permanent abode."

Description of man according to Ali, Abu Turab (as) : "Man is a wonderful creature; he sees through the layers of fat (eyes), hears through a bone (ears) and speaks through a lump of flesh (tongue)."
