For the love of others

 Adawi relates:


“On the day of the Battle of Yarmūk, I went out in search of my cousin. I carried with me a water skin and a small container thinking that if he were still alive, I would give him some water to drink and wipe his face with it. I found him on the verge of death and offered to give him water to drink. He motioned that he wanted it. Then we heard another man moan in pain. My cousin then motioned to me to give the water to him. It turned out that the other man was Hishām son of Al’as, the brother of Amr Alas. I went to him and offered to give him the water, and then another man moan in pain. Hishām motioned to me to take it to him, so I went,only to find that he had already died. Then I returned to Hishām, but he had also died. 
Then I went back to my cousin, but he had died as Well.”

and you still ask how a 40,000 men ended defeating 400,000 at Yarmuk.  ;)

if we didn't commit wrong things

the Prophet said "By Him in Whose hand is my soul , if you had not committed wrong (sins) He would have replaced you by another people who would have committed wrong and then would have sought pardon from Allah, so that He would have forgiven them." [Muslim]

 

 

the Prophet said: "Allah, the Lord of honor & glory, says: he who does good deed shall be rewarded ten times or I may give more, and he who does an evil deed will be punished for only one sin, or I may forgive; and he who comes to Me by a hand's breadth I shall approach him an arm's length, and he who advances towards Me by an arm's length I shall approach him two arm's length; and he who comes to Me walking, I shall go to him running; and he who meets Me with an earthful of sins, provided he has not associated anything with Me, I shall meet him with an equal amount of pardon."

 

 

Abu Hurayrah said: I heard the Prophet saying, "A man committed a sins and then said `O Lord! I have committed a sin, forgive me!' Then his Lord said: `Does My servant know that he has a Lord Who forgives sins and also punishes for it? Lo! I have forgiven My servant.' Then sometime passed and again committed a sin, and said, `O Lord! I have committed another sin, forgive me,' Allah the Exalted said: `Does My servant know that he has a Lord Who forgives sins and also punishes for it? I have forgiven My servant.' Then after some time he committed a sin and said: `O my Lord! I have committed another sin, forgive me for it'! Allah the Exalted said: `Does My servant know that he has a Lord Who forgives sins and punishes for it? I have forgiven My servant three times; let him do what he likes."  [El-Bukhari and Muslim]
