Jami` at-Tirmidhi, Book 47, Hadith 3263 (In-Book) ⓘ
Narrated 'Abdullah: that the Messenger of Allah said: "Every Prophet had a Wali among the Prophets. My Wali is my father Ibrahim the Khalil of my Lord." Then he recited: Verily among mankind who have the best claim to Ibrahim, are those who followed him, and this Prophet and those who have believed. And Allah is the Wali (protector) of the believers (3:68).
حَدَّثَنَا مَحْمُودُ بْنُ غَيْلاَنَ، حَدَّثَنَا أَبُو أَحْمَدَ، حَدَّثَنَا سُفْيَانُ، عَنْ أَبِيهِ، عَنْ أَبِي الضُّحَى، عَنْ مَسْرُوقٍ، عَنْ عَبْدِ اللَّهِ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " إِنَّ لِكُلِّ نَبِيٍّ وُلاَةً مِنَ النَّبِيِّينَ وَإِنَّ وَلِيِّيَ أَبِي وَخَلِيلُ رَبِّي " . ثُمَّ قَرَأَ : (إِنَّ أَوْلَى النَّاسِ بِإِبْرَاهِيمَ لَلَّذِينَ اتَّبَعُوهُ وَهَذَا النَّبِيُّ وَالَّذِينَ آمَنُوا وَاللَّهُ وَلِيُّ الْمُؤْمِنِينَ ).
