Anas b. Malik said:The Apostle of Allah (ﷺ) said: I would be the first intercessor in the Paradise and no apostle amongst the apostles has been testified (by such a large number of people) as I have been testified. And verily there woald be an apostle among the apostles who would be testified to by only one man from his people.
وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا حُسَيْنُ بْنُ عَلِيٍّ، عَنْ زَائِدَةَ، عَنِ الْمُخْتَارِ بْنِ فُلْفُلٍ، قَالَ قَالَ أَنَسُ بْنُ مَالِكٍ قَالَ النَّبِيُّ صلى الله عليه وسلم " أَنَا أَوَّلُ شَفِيعٍ فِي الْجَنَّةِ لَمْ يُصَدَّقْ نَبِيٌّ مِنَ الأَنْبِيَاءِ مَا صُدِّقْتُ وَإِنَّ مِنَ الأَنْبِيَاءِ نَبِيًّا مَا يُصَدِّقُهُ مِنْ أُمَّتِهِ إِلاَّ رَجُلٌ وَاحِدٌ " .
