(And We remove whatever rancour may be in their breasts�) [15:47]. �Abd al-Rahman ibn Hamdan al-�Adl informed us> Ahmad ibn Ja�far ibn Malik> �Abd Allah ibn Ahmad ibn Hanbal> Muhammad ibn Sulayman ibn Khalid al-Fahham> �Ali ibn Hashim> Kathir al-Nawwa� who said: �I said to Abu Ja�far: �So-and-so related to me that he related from �Ali ibn al-Husayn, may Allah be pleased with father and son, that this verse was revealed about Abu Bakr, �Umar and �Ali, may Allah be well pleased with them (And We remove whatever rancour may be in their breasts. As brethren, face to face, (they rest) on couches raised)�. He said: �By Allah, it was revealed about them; and about whom else would it be revealed if not about them�. I asked: �What rancour is that which is referred to here?� He said: �The rancour of the time of ignorance; there was rancour between the Banu Taym, the Banu �Adiyy and the Banu Hashim during the period of ignorance. When these people embraced Islam, they loved each other. In one occasion, Abu Bakr had pain in his waist, so �Ali warmed his hand and applied it on Abu Bakr�s waist. This verse was then revealed� �.
