Sahih al-Bukhari Book 75, Hadith 14
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."
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.'"
Usama bin Zaid said that while he. Sa`d and Ubai bin Ka`b were with the Prophet (ﷺ) a daughter of the Prophet sent a message to him, saying. 'My daughter is dying; please come to us." The Prophet (ﷺ) sent her his greetings and added "It is for Allah what He takes, and what He gives; and everything before His sight has a limited period. So she should hope for Allah's reward and remain patient." She again sent a message, beseeching him by Allah, to come. So the Prophet (ﷺ) got up. and so did we (and went there). The child was placed on his lap while his breath was irregular. Tears flowed from the eyes of the Prophet. Sa`d said to him, "What is this, O Allah's Messenger (ﷺ)?" He said. "This Is Mercy which Allah has embedded in the hearts of whomever He wished of His slaves. And Allah does not bestow His Mercy, except on the merciful among His slaves. (See Hadith No. 373 Vol. 2)
