وَحَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ، حَدَّثَنَا مَهْدِيُّ بْنُ مَيْمُونٍ، عَنْ غَيْلاَنَ، عَنْ عَبْدِ اللَّهِ بْنِ مَعْبَدٍ الزِّمَّانِيِّ، عَنْ أَبِي قَتَادَةَ الأَنْصَارِيِّ، رضى الله عنه أَنَّرَسُولَ اللَّهِ صلى الله عليه وسلم سُئِلَ عَنْ صَوْمِ الاِثْنَيْنِ فَقَالَ " فِيهِ وُلِدْتُ وَفِيهِ أُنْزِلَ عَلَىَّ " .
