It was narrated from Abu Sa‘id al-Khudri (may Allah be pleased with him) that the Prophet (blessings and peace of Allah be upon him) said: “The people of Paradise will enter Paradise and the people of Hell will enter Hell, then Allah (may He be exalted) will say: ‘Bring forth from the Fire whoever had in his heart a mustard seed’s weight of faith.’ They will be brought forth from it having turned black, and will be thrown into the river of al-Haya or al-Hayat (life) – Malik [one of the narrators] was not sure – then they will grow like seeds alongside the course of a stream that flows after it rains. Do you not see how they emerge yellow and curled up?” Wuhayb said: ‘Amr told us it was al-Hayat (life), and he said: “A mustard seed’s weight of good.”.
Commentary :
Allah (may He be glorified) has bestowed upon His slaves His blessings and mercy in this world and the hereafter. In this hadith, the Prophet (blessings and peace of Allah be upon him) explains some of the blessings that Allah will bestow upon them in the hereafter. He tells us that after the believers among the people of Paradise have entered Paradise by the grace and mercy of Allah, and then because of their righteous deeds, and after the people of Hell have entered Hell – so that everyone who deserves to enter it, of people of faith and others, will enter it so that they might be requited for their bad deeds – then Allah will instruct His angels to bring forth from the Fire everyone who did a mustard seed’s worth of the actions of faith, if they had affirmed the oneness of Allah and believed in that which our Prophet (blessings and peace of Allah be upon him) brought. Mustard is a well-known plant the seeds of which are given as a likeness of a very small thing. Here it is used as a metaphor for the tiniest of good deeds.
They will be brought forth from the Fire having turned black; in other words they will have become like coal because of the effect of the fire. Then they will be thrown into the river of al-Haya or al-Hayat (life), which indicates that it will be a cause of life being restored to the bodies of those who are brought forth from Hell. Then they will grow like seeds that are sown alongside the course of a stream that flows after it rains, so they grow quickly but there is some weakness in them; in the beginning they emerge from the earth yellow in colour and beautiful to look at, with their leaves furled. Then they grow taller and the leaves unfurl after that, which increases the fragrant plant in beauty.
This hadith states that the level of faith in the heart may vary, and that the people of faith vary in the level of their faith.
It also indicates that the one who commits sin is exposing himself to punishment in the hereafter and may be admitted to Hell, unless Allah pardons him..
