وعن سهل بن سعد قال: قال رسول الله صلى الله عليه وسلم: “من يضمن لي ما بين لحييه، وما بين رجليه أضمن له الجنة” ((متفق عليه)).
Sahl bin Sa’d (May Allah be pleased with him) reported:
The Messenger of Allah (ﷺ) said, “Whosoever gives me a guarantee to safeguard what is between his jaws and what is between his legs, I shall guarantee him Jannah.”
[Al-Bukhari].
