He who wakes up without any concern for the affairs of Muslims...
He who wakes up without any concern for the affairs of Muslims, is not a Muslim; and he who hears the cry, `O Muslims!' without responding is not a Muslim. On the contrary, to meet the needs of the Muslims and to solve their problems is considered as one of the noblest forms of worship. The Prophet is reported to have said: من مشى في حاجة أخيه ساعة من ليل أو نهار, قضاها أو لم يقضها, كان خيرا له من اعتكاف شهرين.
An hour covered on foot, at night or during day, in the effort to help one's brother meet his need, is better than two months of i`tikaf (spiritual retirement), regardless of whether or not one succeeds in one's effort.
Negligence in Carrying Out the Duty of "Al-amr bil ma'ruf wal nahy 'an al-munhar" Failure to carry out the duty of al- amr bil-ma`ruf wal-nahy `an il munkar is an unforgivable sin caused either by moral weakness or lack of attention to one's religious duties, and results in the spread of immorality, corruption, injustice, and other forms of indecency throughout society.
"Commanding others to do their Divine duties and forbidding them from committing illegitimate deeds" is an obligatory duty of every Muslim, and has stages and conditions which have been explained in detail in books dealing with Islamic fiqh. Since what we are concerned with here are the individual's duties with regard to his relationship with others, this brief mention of this duty is sufficient.
Unsociableness This vice is caused either by hostility, vengefulness, jealousy, or miserliness, and, therefore, it belongs either to the Power of Passion, or the Power of Anger. It has been condemned in numerous traditions. The opposite of this vice is the virtue of sociability, hospitality and friendliness, which is conductive to expansion of warm, brotherly relations throughout the community. This virtue is highly recommended by Islam.
Breaking Ties with One's Family and Kin This vice is a branch of unsociableness, but is far uglier and more harmful. The opposite of this vice is the virtue of maintaining close cordial family ties. A large number of traditions which can be found in the books on hadith deal with this subject.
Being undutiful to Parents This is the worst form that the vice of breaking off ties with one's family can take, and according to severely worded traditions, it is the cause of severe chastisement both in this world and the next. As opposed to this, kind and loving behaviour towards one's family is considered to be one of the highest of human virtues.
