Sahih al-Bukhari, Hadith 3933 ⓘ
Narrated `Abdur-Rahman bin Humaid Az-Zuhri: I heard `Umar bin `Abdul-Aziz asking As-Sa'ib, the nephew of An-Nimr. "What have you heard about residing in Mecca?" The other said, "I heard Al-Ala bin Al-Hadrami saying, Allah's Messenger said: An Emigrant is allowed to stay in Mecca for three days after departing from Mina (i.e. after performing all the ceremonies of Hajj)"
حَدَّثَنِي إِبْرَاهِيمُ بْنُ حَمْزَةَ، حَدَّثَنَا حَاتِمٌ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ حُمَيْدٍ الزُّهْرِيِّ، قَالَ سَمِعْتُ عُمَرَ بْنَ عَبْدِ الْعَزِيزِ، يَسْأَلُ السَّائِبَ ابْنَ أُخْتِ النَّمِرِ مَا سَمِعْتَ فِي، سُكْنَى مَكَّةَ قَالَ سَمِعْتُ الْعَلاَءَ بْنَ الْحَضْرَمِيِّ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " ثَلاَثٌ لِلْمُهَاجِرِ بَعْدَ الصَّدَرِ " .
