حَدَّثَنَا إِبْرَاهِيمُ بْنُ الْمُنْذِرِ الْحِزَامِيُّ، حَدَّثَنَا مُحَمَّدُ بْنُ طَلْحَةَ التَّيْمِيُّ، حَدَّثَنِي عَبْدُ الرَّحْمَنِ بْنُ سَالِمِ بْنِ عُتْبَةَ بْنِ عُوَيْمِ بْنِ سَاعِدَةَ الأَنْصَارِيُّ، عَنْ أَبِيهِ، عَنْ جَدِّهِ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ ‏ "‏ عَلَيْكُمْ بِالأَبْكَارِ فَإِنَّهُنَّ أَعْذَبُ أَفْوَاهًا وَأَنْتَقُ أَرْحَامًا وَأَرْضَى بِالْيَسِيرِ ‏" ‏ ‏.‏
