It is unlawful for a Muslim to desert his fellow Muslim for more than three nights. As they meet, both of them turn their backs on each other. But the best of them is the one who starts by greeting the other

Explanation

The Prophet (may Allah's peace and blessings be upon him) forbade that a Muslim should desert his fellow Muslim for more than three nights. None of them greets the other or talks to him when they meet. The best of such two estranged persons is the one who tries to end their estrangement, so he greets the other first. The kind of desertion intended in this Hadīth is what a person engages in for his own sake. However, a person may desert others for the sake of Allah Almighty, like deserting sinners, heretic innovators, and bad companions. This does not have a time limit. Instead, it is contingent on a cause and should end when the cause is no longer there.

Benefits

• It is permissible to desert someone for three days or less. Taking human nature into consideration, desertion for this period of three days is allowed so as to give a chance for the cause behind this to go away.
• The Hadīth points out the merit of the greeting of peace and that it removes ill feelings and is a sign of love.
• Islam is keen on the existence of brotherliness and friendliness among its followers.
