وَعَنْ أَيُّوبَ بْنِ مُوسَى عَنْ أَبِيهِ عَنْ جَدِّهِ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «مَا نَحَلَ وَالِدٌ وَلَدَهُ مِنْ نُحْلٍ أَفْضَلَ مِنْ أَدَبٍ حَسَنٍ» . رَوَاهُ التِّرْمِذِيُّ وَالْبَيْهَقِيُّ فِي «شُعَبِ الْإِيمَانِ» وَقَالَ التِّرْمِذِيُّ: هَذَا عِنْدِي حَدِيث مُرْسل
Ayub bin Musa narrates from his father, and he from his grandfather, that the Messenger of Allah, peace and blessings be upon him, said: "The best gift parents give to their children is their good upbringing." Tirmidhi, Bayhaqi in Shu'ab al-Iman. And Imam Tirmidhi said: In my view, this hadith is mursal. Its chain is weak, narrated by Tirmidhi and Bayhaqi in Shu'ab al-Iman.
