One day the Prophet of Islam (PBUH) was delivering a sermon in a loud voice and the women who were in the houses around that area could hear his voice.
The Prophet (PBUH) said: O’ the group (of people) who are believers by tongue and not by heart, do not gossip about Muslims, and do not try to find their faults, because whoever is trying to find faults with Muslim brothers/sisters, Allah (SWT) will find faults with him/her in order to embarrass him/her in his/her own house [1].
