عَنِ ابْنِ الْفِرَاسِيِّ أَنَّ الْفِرَاسِيَّ قَالَ: قُلْتُ لِرَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَسْأَلُ يَا رَسُولَ اللَّهِ؟ فَقَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «لَا وَإِن كنت لابد فسل الصَّالِحين» . رَوَاهُ أَبُو دَاوُد وَالنَّسَائِيّ

Thauban reported God’s messenger as saying, "If anyone guarantees me that he will not beg from people, I will guarantee him paradise.” Thauban said that he would, and he never asked anyone for anything. Abu Dawud and Nasa'i transmitted it.
