The meanings of a Hadith
The Prophet (saw) and Abu Bakr (ra) were together at one place in Makkah (before the Hijra), when some non-believers came and started verbal abuse of Abu Bakr (ra). At first he remained silent but when the abuse crossed the limits of tolerance, he started to reply.
The Prophet (saw) left without saying a word.
When they met again, Abu Bakr (ra) asked the Prophet (saw) why he had remained with him during the abuse against his friend, but left as soon as he had started giving a reply.
The Prophet (saw) said:
When you were silent, there was an angel (or maybe more, it is timbuktu's forgetfulness) who had been assigned to reply on your behalf. When you started replying, he left, so I did too.
Who can give a more befitting reply? Us or an angel assigned by Allah (swt).
For every moment of silence in reply to abuse or spreading of falsehood, we gain merits which will come in useful in the Hereafter.
I saw my mother put up with a lot with dignity. She did try to get us our rights, but in a dignified way. She would never utter a word that could be hurtful, even to the most abusive of people. She herself did, and made us fulfill all the rights of others, even when they had clearly abrogated our rights, and had tried to belittle us in front of others.
