Being cleared of the sin of deserting fellow Muslim brothers

A: Firstly, Islam enjoins the promotion of love among Muslims. It urges Muslims to love one another, be compassionate towards one another, and uphold ties with one another so that their affairs will be set right, and they will be united against their enemies. Islam warns Muslims against enmity and hatred, and forbids them to forsake one another or cut off ties with one another. Abandoning a Muslim for more than three days is Haram (Prohibited). It was reported in the Two Sahih (authentic) Books of Hadith (i.e. Al-Bukhari and Muslim) and other Books of Hadith, on the authority of Abu Ayyub Al-Ansary (may Allah be pleased with him) that the Messenger of Allah (peace be upon him) stated, It is not lawful for a Muslim to turn his back on his brother for more than three nights, the one turning one way and the other turning another way when they meet. The better of the two is one who first greets the other. It is recorded in Sunan Al-Tirmidhy, on the authority of Abu Hurayrah that the Messenger of Allah (peace be upon him) said, Beware of spoiling relations with other people for this is a cause of erosion. i.e. it causes the religion to erode. (Part No. 26; Page No. 128) Secondly, a Muslim should go to his fellow brother and greet him, even if there has been a dispute. Moreover, a Muslim should treat his fellow Muslim kindly so as to make reconciliation easy. This earns great reward, and secures one from incurring sin. Abu Dawud related on the authority of `Aishah (may Allah be pleased with her) that the Messenger of Allah (peace be upon him) stated, It is not lawful for a Muslim to turn his back on his brother for more than three nights. When one of them meets the other and greets him three times but the latter does not respond, he will be liable to the sin of his act." It is recorded in Sahih Muslim and other books of Hadith, on the authority of Abu Hurayrah (may Allah be pleased with him) that the Prophet (peace be upon him) stated, The deeds are presented on every Thursday and Monday and Allah, the Exalted and Glorious, grants pardon to every person who does not associate anything with Allah, except the person in whose (heart) there is rancor against his brother. It would be said 'Put both of them off until they are reconciled'. However, if the wronged feels that trying to make peace with the wrongdoer will make him increase in wrongdoing, it will be better to abandon him to avoid evil and to preserve dignity.Thirdly, Muslims should reconcile between their brothers, especially those who are disputing. They should encourage them to reconcile and point out the merits of forgiveness and the great reward it carries. Allah (Exalted be He) states, ...but whoever forgives and makes reconciliation, his reward is with Allâh. (Part No. 26; Page No. 129)  It is recorded in Sunan Al-Tirmidhi and Abu Dawud on the authority of Abu Al-Darda' (may Allah be pleased with him) that the Messenger of Allah (peace be upon him) stated, "Shall I inform you what is better in degree than Fasting, Praying, and giving in charity?" They said, "Yes, O Messenger of Allah!" He said, "Reconciling between people, as spoiling what is between them is destructive." May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
