Hadith 3.3
Marriage
Abu Sa'id and Ibn ‘Abbas reported God’s Messenger as saying, “He who has a son born to him should give him a good name and a good education and marry him when he reaches puberty. If he does not marry him when he reaches puberty and He commits sin, its guilt rests only upon his father." Baihaqi transmitted in <i>Shu'ab al-iman</i>.
وَعَنْ أَبِي سَعِيدٍ وَابْنِ عَبَّاسٍ قَالَا: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «من وُلِدَ لَهُ وَلَدٌ فَلْيُحْسِنِ اسْمَهُ وَأَدَبَهُ فَإِذَا بَلَغَ فَلْيُزَوِّجْهُ فَإِنْ بَلَغَ وَلَمْ يُزَوِّجْهُ فَأَصَابَ إِثْمًا فَإِنَّمَا إثمه على أَبِيه»
