It is narrated from ‘Ubadah bin Samit (may Allah be pleased with him) that the Prophet (peace and blessings of Allah be upon him) said:“Guarantee me six things from yourselves and I will guarantee you Paradise: When you speak, speak the truth; when you make a promise, fulfill it; when something is entrusted to you, return it; guard your private parts; lower your gaze; and restrain your hands (from injustice).”Its chain is weak. Narrated by Ahmad and al-Bayhaqi in Shu’ab al-Iman.
