The Messenger of Allah (sal Allahu alaihi wa sallam) said: “The most hated man (person) to Allah is the one who is the most quarrelsome of the opponents.” [Sahih Bukhari]
Quarreling never settles disputes. Extricate yourself from quarrels as soon as possible. Allah (subhana wa ta’ala) does not like either of quarreling opponents, but the more quarrelsome one is the more hated to Allah (subhana wa ta’ala).
Keep this checklist in mind if a quarrel seems to be in the offing:
1. Let your opponent have the last word (ostensibly). In reality, the one who is quiet is the one who is defended eloquently by angels.
2. Stop trying to prove that you’re right.
3. Accept blame where the fault is yours.
4. State your position just once and then listen.
5. Before the blaming becomes unbearable, politely, either change the topic or physically leave the place of argument.
6. Remember that all cases will be reopened and settled on the Day of Judgement, and on that day none will be able to lie, trick or deceive in any way, to support their position.
The Prophet (peace be upon him) said: Whoever conceals (the fault of) a Muslim in this world, Allah will conceal him (his faults) in this world and in the hereafter.
