Yahya related to me from Malik from Abu'n-Nadr, the mawla of Umar
ibn Ubaydullah that A'isha bint Talha told him that she was once with
A'isha, the wife of the Prophet, may Allah bless him and grant him
peace, and her husband, who was fasting, came and visited her there.
(He was Abdullah ibn Abd ar-Rahman ibn Abi Bakras-Siddiq.) A'isha said
to him, "What's stopping you from coming close to your wife and
kissing her and joking with her?" He said, "Can I kiss her when I am
fasting?" She said, "Yes."
Muwatta Malik Book 18, Hadith 17
Allah's Messenger (ﷺ)s said, "When a slave (of Allah) commits illegal sexual
intercourse, he is not a believer at the time of committing it; and if
he steals, he is not a believer at the time of stealing; and if he
drinks an alcoholic drink, when he is not a believer at the time of
drinking it; and he is not a believer when he commits a murder,"
'Ikrima said: I asked Ibn Abbas, "How is faith taken away from him?"
He said, Like this," by clasping his hands and then separating them,
and added, "But if he repents, faith returns to him like this, by
clasping his hands again.
Sahih al-Bukhari Book 86, Hadith 38
Yahya related to me from Malik from Hisham ibn Urwa from his
father from A'isha, the wife of the Prophet, may Allah bless him and
grant him peace, that al-Harith ibn Hisham asked the Messenger of
Allah, may Allah bless him and grant him peace, "How does the
revelation come to you?" and the Messenger of Allah, may Allah bless
him and grant him peace, said, "Sometimes it comes to me like the
ringing of a bell, and that is the hardest for me, and when it leaves
me I remember what it has said. And sometimes the angel appears to me
in the likeness of a man and talks to me and I remember what he says."
A'isha added, "I saw it coming down on him on an intensely
cold day, and when it had left him his forehead was dripping with
sweat."
Muwatta Malik Book 15, Hadith 8
