‘Abd ar-Rahman b. Salim b. ‘Utba b.'Uwaim b. Sa'ida al-Ansari, on his father’s authority, told that his grandfather reported God’s Messenger as saying, “Marry virgins, for they have the sweetest mouths, the most prolific wombs, and are most satisfied with little.” Ibn Majah transmitted in <i>mursal</i> form.

وَعَنْ عَبْدِ الرَّحْمَنِ بْنِ سَالِمِ بْنِ عُتْبَةَ بْنِ عُوَيْمِ بْنِ سَاعِدَةَ الْأَنْصَارِيِّ عَنْ أَبِيهِ عَنْ جَدِّهِ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «عَلَيْكُمْ بِالْأَبْكَارِ فَإِنَّهُنَّ أَعْذَبُ أَفْوَاهًا وَأَنْتَقُ أَرْحَامًا وَأَرْضَى بِالْيَسِيرِ» . رَوَاهُ ابْنُ مَاجَه مُرْسلا
