“Shall I tell you of a thing which when ye do, ye will love one another? Extend greetings among yourselves”; – thus spoke the Prophet of Mercy(S.A.W).Here are some Ahadith.
“When one of you sees a bier, and does not walk with it, let him stand up until it has passed away or is put down.”(‘Amir b. Rabi’ah in Bukhari, Muslim; Abu Da’ud; Tirmidhi; Nasa’i)
A bier was passing, and the Apostle stood up for it, and we also stood up with him, and said, “O Apostle of Allah! Verily this is a jewish woman (who is dead).” The Apostle said, “Verily death is terrible; so when ye see a bier, stand up.” (Jabir in Bukhari; Muslim)
A bier passed by the Apostle, and he stood up. It was said to him, “Verily it is the bier of a Jew.” The Apostle said, “Was it not a living thing?”(‘Abdal-Rahman b. Abu-Layla in Bukhari; Muslim)
“The best of actions is to love for (the sake of) Allah and yet hate for (the sake of Allah).”(Abu-Dharr in Abu Da’ud)
“Allah accepts only what is good.“(Abu-Hurayrah in Bukhari; Muslim)
“Verily, men will follow you, and verily men will come to you from (all) quarters of the earth to understand religion; so when they come to you, enjoin goodness upon them.” (Abu-Sa’id al-Khudriy in Tirmidhi)
“The liberal man is near to Allah, near paradise, near (the hearts of) men, farther from the fire (of hell); and the miser is farther from Allah, farther from paradise, farther from (the hearts of) men, near the fire (of hell); and an ignorant liberal man is more beloved of Allah than a niggardly worshipper.” (Abu-Hurayrah in Tirmidhi)
“By him in whose hand my soul is! Ye shall by no means enter paradise until ye believe, and ye shall by no means believe until ye love one another. (Abu-Hurayrah in Muslim; Abu Da’ud; Tirmidhi)
“Shall I tell you of a thing which when ye do, ye will love one another? Extend greetings among yourselves.”(Abu-Hurayrah in Muslim)
“There are some among the servants of Allah who are neither prophets nor martyrs, but whom the prophets and martyrs will yet envy on the day of resurrection because of the position they shall have from Allah: these are the people who love others, not their kin only, for the mercy that they expect from Allah. And by Allah! Their faces shall shine with light, and they shall be in the light of Allah: they shall not fear when all (other) men shall fear, nor shall they grieve when all (other) men shall grieve.” (‘Umar b. al-Khattab in Abu Da’ud)
