Arabic hadith text
حَدَّثَنَا مُحَمَّدُ بْنُ كَثِيرٍ، أَخْبَرَنَا سُفْيَانُ، عَنِ ابْنِ الْمُنْكَدِرِ، قَالَ سَمِعْتُ جَابِرًا ـ رضى الله عنه ـ يَقُولُمَا سُئِلَ النَّبِيُّ صلى الله عليه وسلم عَنْ شَىْءٍ قَطُّ فَقَالَ لاَ.
Translation
Narrated Jabir
Never was the Prophet (ﷺ) asked for a thing to be given for which his answer was 'no'.
