وَعَنْهُ قَالَ : { كَانَ رَسُولُ اَللَّهِ - صلى الله عليه وسلم -يَأْمُرُ بِالْبَاءَةِ , وَيَنْهَى عَنِ التَّبَتُّلِ نَهْيًا شَدِيدًا , وَيَقُولُ :" تَزَوَّجُوا اَلْوَدُودَ اَلْوَلُودَ . إِنِّي مُكَاثِرٌ بِكُمُ اَلْأَنْبِيَاءَ يَوْمَ اَلْقِيَامَةِ } رَوَاهُ أَحْمَدُ , وَصَحَّحَهُ اِبْنُ حِبَّانَ [1] .
Narrated [Anas bin Malik (RA)]: Allah's Messenger (ﷺ) used to command us to marry and sternly forbid celibacy and say, "Marry women who are beloved (due to their good characteristics), prolific in bearing children, for I shall outnumber the Prophets by you on the Day of Resurrection." [Reported by Ahmad and Ibn Hibban graded it Sahih (authentic)].
