When you see your brother fall, save him, rescue him, let him not fall onto the ground. His fall is the collapse of the whole Ummah. Umar (RA) said this when he heard of a young man who had problems with alcohol. The people did not want anything to do with this man and felt he would bring him down. See what Umar did to save this man. It is powerful and very emotional and it is how Muslims used to deal with those who strayed away, with mercy and kindness.
