Some beautiful reminders in hadith:
Narrated Abu Hurairah:
I heard Allah's Apostle saying, Allah divided Mercy into one-hundred parts and He kept its ninety-nine parts with Him and sent down its one part on the earth, and because of that, its one single part, His creations are Merciful to each other, so that even the mare lifts up its hoofs away from its baby animal, lest it should trample on it."
The Prophet said, "Beware of suspicion, for suspicion is the worst of false tales; and do not look for the others' faults and do not spy, and do not be jealous of one another, and do not desert (cut your relation with) one another, and do not hate one another; and O Allah's worshipers! Be brothers (as Allah has ordered you!")
Narrated Abu Huraira:
Allah's Apostle said, "The strong is not the one who overcomes the people by his strength, but the strong is the one who controls himself while in anger."
Narrated Al-Walid bin 'Aizar:
I heard Abi Amr 'Ash-Shaibani saying, "The owner of this house." he pointed to 'Abdullah's house, "said, 'I asked the Prophet 'Which deed is loved most by Allah?" He replied, 'To offer prayers at their early (very first) stated times.' " 'Abdullah asked, "What is the next (in goodness)?" The Prophet said, "To be good and dutiful to one's parents," 'Abdullah asked, "What is the next (in goodness)?" The Prophet said, To participate in Jihad for Allah's Cause." 'Abdullah added, "The Prophet narrated to me these three things, and if I had asked more, he would have told me more."
