Sahih al-Bukhari Book 75, Hadith 13
I heard Allah's Messenger (ﷺ) saying, "Allah said, 'If I deprive my slave of his two beloved things (i.e., his
eyes) and he remains patient, I will let him enter Paradise in compensation for them.'"
Ibn `Abbas said to me, "Shall I show you a woman of the people of Paradise?" I said, "Yes." He said, "This black lady came to the Prophet (ﷺ) and said, 'I get attacks of epilepsy and my body becomes uncovered; please invoke Allah for me.' The Prophet (ﷺ) said (to her), 'If you wish, be patient and you will have (enter) Paradise; and if you wish, I will invoke Allah to cure you.' She said, 'I will remain patient,' and added, 'but I become uncovered, so please invoke Allah for me that I may not become uncovered.' So he invoked Allah for her."
Narrated 'Ata:
That he had seen Um Zafar, the tall black lady, at (holding) the curtain of the Ka`ba.
When Allah's Messenger (ﷺ) emigrated to Medina, Abu Bakr and Bilal got a fever. I entered upon them and asked, "O my father! How are you? O Bilal! How are you?" Whenever fever attacked Abu Bakr, he would recite the following poetic verses: 'Everybody is staying alive among his people, yet death is nearer to him than his shoe laces." And whenever the fever deserted Bilal, he would recite (two poetic lines): 'Would that I could stay overnight in a valley wherein I would be surrounded by Idhkhir and Jalil (two kinds of good smelling grass). Would that one day I would drink of the water of Majinna and would that Shama and Tafil (two mountains at Mecca) would appear to me.' Then I came and informed Allah's Messenger (ﷺ) about that, whereupon he said, "O Allah! Make us love Medina as much or more than we love Mecca. O Allah! Make it healthy and bless its Mudd and Sa for us, and take away its fever and put it in Al Juhfa."
