There were people in Medina whose provision would come to them at night, though they did not know from whom it came. When Zayn al-Ābidīn (1) died, it ceased coming to them, (2) and they realized that it had come from him. (3)
His son Muhammad al-Bāqir (4) surpassed all people in asceticism and worship. Prostration had furrowed his forehead, and he was the most learned [among the people] (5) of his time. The Messenger of Allah—may Allah bless him and grant him peace—had named him al-Bāqir.
Jābir ibn Abd Allāh al-Ansārī came to him (6) while he was still a young boy at the Quran school and said to him, “Your grandfather, the Messenger of Allah—may Allah bless him and grant him peace—sends you his greetings of peace.”
He replied, “And peace be upon my grandfather.”
Jābir was asked, “How can this be?”
He said: (7) “I was sitting with the Messenger of Allah—may Allah bless him and grant him peace—while al-Husayn was in his lap and he was playing with him. (8) He said, ‘O Jābir, a son named Alī will be born to him. When (9) the Day of Resurrection comes, a herald will call out: “Let the master of the worshippers arise!” His son will then arise. He, in turn, will have a son named Muhammad al-Bāqir, who will thoroughly lay knowledge open. (10) When you see him, convey my greetings of peace to him.’” (11)
Abū Hanīfa and others narrated from him.
