Sunan Ibn Majah 1861
It was narrated from Abdur-Rahman bin Salim bin Utbah bin Salim bin Uwaim bin Sa'idah Al-Ansari, from his father that:
his grandfather said: “The Messenger of Allah said: 'You should marry virgins, for their mouths are sweeter, their wombs are more prolific and they are satisfied with less.'”
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 ‏"‏ ‏.‏
