Imam Musa al-Kazim’s (‘a) mother and Imam Jafar al-Sadiq’s (‘a) wife, Umme Hameeda was sitting in her home, bereaved by the passing away of her beloved husband and Imam.
She noticed a very close friend of her husband, Abu Basir, among those who had come to condole with the family of the Imam (‘a). They both wept silently. Umme Hameeda then addressed Abu Basir. “During the last moments of his life, the Imam (‘a) suddenly opened his eyes and insisted upon seeing all his relatives, friends and close associates as soon as possible. We were much concerned as the manner of demanding their presence was almost a command. All those who could, arrived immediately. On seeing them, the Imam said,‘Our intercession will certainly not reach those who disregard prayer.’ These were his last words of advice to all who loved him.”
