Sahih al-Bukhari 3786 (Book 64, Hadith 2)

Narrated `Abdullah bin Mas`ud: From Sa`d bin Mu`adh: Sa`d bin Mu`adh was an intimate friend of Umaiya bin Khalaf and whenever
Umaiya passed through Medina, he used to stay with Sa`d, and whenever Sa`d went to Mecca, he used
to stay with Umaiya. When Allah’s Messenger (ﷺ) arrived at Medina, Sa`d went to perform `Umra and
stayed at Umaiya’s home in Mecca. He said to Umaiya, “Tell me of a time when (the Mosque) is
empty so that I may be able to perform Tawaf around the Ka`ba.” So Umaiya went with him about
midday. Abu Jahl met them and said, “O Abu Safwan! Who is this man accompanying you?” He said,
“He is Sa`d.” Abu Jahl addressed Sa`d saying, “I see you wandering about safely in Mecca inspite of
the fact that you have given shelter to the people who have changed their religion (i.e. became
Muslims) and have claimed that you will help them and support them. By Allah, if you were not in the
company of Abu Safwan, you would not be able to go your family safely.” Sa`d, raising his voice,
said to him, “By Allah, if you should stop me from doing this (i.e. performing Tawaf) I would
certainly prevent you from something which is more valuable for you, that is, your passage through
Medina.” On this, Umaiya said to him, “O Sa`d do not raise your voice before Abu-l-Hakam, the chief
of the people of the Valley (of Mecca).” Sa`d said, “O Umaiya, stop that! By Allah, I have heard
Allah’s Messenger (ﷺ) predicting that the Muslim will kill you.” Umaiya asked, “In Mecca?” Sa`d said, “I do
not know.” Umaiya was greatly scared by that news.
When Umaiya returned to his family, he said to his wife, “O Um Safwan! Don’t you know what Sa`d
told me? “She said, “What has he told you?” He replied, “He claims that Muhammad has informed
them (i.e. companions that they will kill me. I asked him, ‘In Mecca?’ He replied, ‘I do not know.”
Then Umaiya added, “By Allah, I will never go out of Mecca.” But when the day of (the Ghazwa of)
Badr came, Abu Jahl called the people to war, saying, “Go and protect your caravan.” But Umaiya
disliked to go out (of Mecca). Abu Jahl came to him and said, “O Abu Safwan! If the people see you
staying behind though you are the chief of the people of the Valley, then they will remain behind with
you.” Abu Jahl kept on urging him to go until he (i.e. Umaiya) said, “As you have forced me to
change my mind, by Allah, I will buy the best camel in Mecca. Then Umaiya said (to his wife). “O
Um Safwan, prepare what I need (for the journey).” She said to him, “O Abu Safwan! Have you
forgotten what your Yathribi brother told you?” He said, “No, but I do not want to go with them but
for a short distance.” So when Umaiya went out, he used to tie his camel wherever he camped. He
kept on doing that till Allah caused him to be killed at Badr.
