"Islam has been built upon five things - on testifying that there is no god save Allah, and that Muhammad is His Messenger; on performing salah; on giving the zakah; on Hajj to the House; and on fasting during Ramadhan." Al-Bukhari & Muslim.

Abu Sirma reported that when the time of the death of Abu Ayyub Ansari drew near, he said: I used to conceal from you a thing which I heard from Allah's Messenger (may peace be upon him) and I heard Allah's Messenger (may peace be upon him) as sayirig: Had you not committed sins, Allah would have brought into existence a creation that would have committed sin (and Allah) would have forgiven them.

'Umar b. Khattab reported that there were brought some prisoners to Allah's Messenger (may peace be upon him) amongst whom there was also a woman, who was searching (for someone) and when she found a child amongst the prisoners, she took hold of it, pressed it against her chest and provided it suck. Thereupon Allah's Messenger (may peace be upon him) said: Do you think this woman would ever afford to throw her child in the Fire ? We said: By Allah, so far as it lies in her power, she would never throw the child in Fire.' Thereupon Allah's Messenger (may peace be upon him) said: Allah is more kind to His servants than this woman is to her child.

Abu Huraira reported Allah's Messenger (may peace be upon him) as saying : There are one hundred (parts of) mercy for Allah and He has sent down out of these one part of mercy upon the jinn and human beings and the insects and it is because of this (one part) that they love one another, show kindness to one another and even the beast treats its young one with affection, and Allah has reserved ninetynine parts of mercy with which He would treat His servants on the Day of Resurrection.
