Hadis al-Rasool ﷺ

Hazrat Abu Umamah (may Allah be pleased with him) narrated that the Messenger of Allah (PBUH) said: "Whoever usurped the right of a Muslim through his oath, Allah has made the fire obligatory for him and made Paradise forbidden for him." A person submitted to Him (PBUH): "Even if it is an insignificant thing, O Messenger of Allah!" He (PBUH) said: "Even if it is a branch of a Peelu tree."
