Out of that affection and thoughtfulness he felt towards the faithful, the Prophet (PBUH) asked Allah to forgive their mistakes. Allah's commands to the Prophet (PBUH) on that subject take the following form:
O Prophet! When women who believe come to you pledging allegiance to you on the grounds that they will not associate anything with Allah or steal or fornicate or kill their children or give a false ascription of paternity-making up lies about their bodies-or disobey you in respect of anything right, then accept their pledge and ask forgiveness for them. Allah is Ever-Forgiving, Most Merciful. (Surat al-Mumtahana: 12)
Know then that there is no god except Allah and ask forgiveness for your wrongdoing, and for the men and women who believe. Allah knows both your activity and your repose. (Surah Muhammad: 19)
"... If they ask your permission to attend to their own affairs, give permission to any of them you please; and ask Allah's forgiveness for them. Allah is Ever-Forgiving, Most Merciful." (Surat an-Nur: 62)
In another verse, Allah told the Prophet (PBUH) to pray for the faithful:
... Pray for them. Your prayers bring relief to them. Allah is All-Hearing, All-Knowing. (Surat at-Tawba: 103)
As this verse reveals, the Prophet (PBUH)'s prayers brought the faithful peace and tranquility. It must not be forgotten that only Allah gives peace and tranquility to the heart. Allah makes the prayers of His Messenger (PBUH), whom He has appointed as guardian and protector of the faithful, a means whereby they come by comfort and ease. Our Lord's love and compassion, and His protection and mercy for the faithful is most clearly represented in the morality of the Prophet (PBUH).
Those who do good will have the best and more! Neither dust nor debasement will darken their faces. They are the Companions of the Garden, remaining in it timelessly, for ever.(Surah Yunus: 26)
