Covering up the shortcomings and faults of people is an excellent manner. That is why this quality is very much liked by Almighty Allah. On the Day of Resurrection, Allah will give a matching reward to that man who has such a quality, which means that Allah will forgive his sins and will not call him to account for his sins. If at all He will do so, He will not do it publicly so that he is not embarrased before others. Then Allah may forgive him or send him to Hell for a short while.
