Narrated by Aisha (radiallaahu `anhaa)
Once Allah’s Apostle (sallallaahu `alayhi wasallam) heard the loud voices of some opponents quarreling at the door. One of them was appealing to the other to deduct his debt and asking him to be lenient but the other was saying, “By Allah I will not do so.” Allah’s Apostle (sallallaahu `alayhi wasallam) went out to them and said, “Who is the one who was swearing by Allah that he would not do a favor?” That man said, “I am that person, O Allah’s Apostle! I will give my opponent whatever he wishes.”
There’s something really oxymoron-ish about swearing by Allah to not do something good. The two just don’t go together. Often times we say things in anger and heat of the moment that we come to regret later. If only we thought once before speaking. If only there was someone to correct us right there on the spot. Alas, the wicked things that are tongues are!
One of the noblest traits of one’s character is to admit mistakes and make amends. The good thing about this world is that we always have a second, third, fourth chance to start afresh – as long as death doesn’t come knocking.
So if you slipped, if you were in error, you need to take the first step towards forgiveness. Admit your fault and right the wrong. You still have a chance.
