حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا حَاتِمُ بْنُ إِسْمَاعِيلَ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ حُمَيْدٍ الزُّهْرِيِّ، قَالَ سَأَلْتُ السَّائِبَ بْنَ يَزِيدَ مَاذَا سَمِعْتَ فِي، سُكْنَى مَكَّةَ قَالَ سَمِعْتُ الْعَلاَءَ بْنَ الْحَضْرَمِيِّ، يَقُولُ قَالَ النَّبِيُّ ـ صلى الله عليه وسلم ـ " ثَلاَثًا لِلْمُهَاجِرِ بَعْدَ الصَّدَرِ " .
