وَعَنْ ثَوْبَانَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَنْ يَكْفُلُ لِي أَنْ لَا يَسْأَلَ النَّاسَ شَيْئًا فَأَتَكَفَّلَ لَهُ بِالْجَنَّةِ؟» فَقَالَ ثَوْبَانُ: أَنَا فَكَانَ لَا يَسْأَلُ أَحَدًا شَيْئا. 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.
