وَعَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «أَنَا أَوَّلُ شَفِيعٍ فِي الْجَنَّةِ لَمْ يُصَدَّقْ نَبِيٌّ مِنَ الْأَنْبِيَاءِ مَا صُدِّقْتُ وَإِنَّ مِنَ الْأَنْبِيَاءِ نَبِيًّا مَا صَدَّقَهُ مِنْ أُمَّته إِلَّا رجل وَاحِد» . رَوَاهُ مُسلم

He reported God’s messenger as saying, “I shall be the first intercessor in paradise, no prophet having been believed to the extent I have. Among the prophets there is one who was believed by only one man out of his people.” Muslim transmitted it.
