Narrated Anas RA: It was said to the Prophet(SAWW) "Would that you see Abdullah bin Ubai." So, the Prophet(SAWW) went to him, riding a donkey, and the Muslims accompanied him, walking on salty barren land. When the Prophet(SAWW) reached ‘Abdullah bin Ubai, the latter said, "Keep away from me! By Allah, the bad smell of… your donkey has harmed me." On that an Ansari man said (to ‘Abdullah), "By Allah! The smell of the donkey of Allah’s Apostle is better than your smell." On that a man from ‘Abdullah’s tribe got angry for ‘Abdullah’s sake, and the two men abused each other which caused the friends of the two men to get angry, and the two groups started fighting with sticks, shoes and hands. We were informed that the following Divine Verse was revealed (in this concern):– "And if two groups of Believers fall to fighting then, make peace between them." (49.9)
Narrated Um Kulthum bint Uqba RA: That she heard Allah’s Apostle saying, "He who makes peace between the people by inventing good information or saying good things, is not a liar."
Sayyiduna Abu Umamah Al-Bahili (Radhi Allaho anho) narrates that Rasulullah (Sallallahu Alaihi wa Aalihi wa Sallam) said: "The one who recites Ayatul Kursi after each of the obligatory prayers,then death will be the only thing preventing him from entering Paradise." [Ibn Sunni, Ibn Hibban]
Bukhari: Severing ties of kinship is such a grievous sin that none stained with it will be able to enter Paradise. However, when one is cleansed after undergoing punishment, or is pardoned by Allah Subhanahu wa Ta’ala for some reason or without any reason, then he will be able to enter Paradise.(Ma’ariful Hadith)
