Quran's Tafhim ( explanation)
*18) This verse establishes a universal brotherhood of aII the Muslims of the world, and it is by virtue of this that the sort of fraternity that exists among the Muslims exists among the followers of no other religion and creed. The importance of this Command and its demands have been explained by the Holy Prophet in many of his Traditions from which one can understand its full significance and spirit - Hadrat Jarir bin 'Abdullah says: The Holy Prophet took a pledge from Me on three things: That I will establish the Prayer; that I will continue to pay the zakat: and that I will remain a well-wisher of every Muslim. " (Bukhari: Kitab-al-Iman. According to Hadrat 'Abdullah bin Mas'ud, the Holy Prophet said: "To abuse a Muslim is sinful and to fight him disbelief." In Musnad Ahmad a tradition bearing on the same subject has also been related by Hadrat Said bin Malik on the authority of his father. Hadrat-Abu Hurairah relates that the Holy Prophet said: "The life, property and honour of every Muslim is forbidden to every other Muslim. " (Muslim: Kitab-al-Birr was Silah; Tirmidhi: Abwab-al-Birr was-Silah). Hadrat Abu Said Khudri and Hadrat Abu Hurairah say that the Holy Prophet said: "A Muslim is a brother to the other Muslim: he does not treat him unjustly; he dces not leave him alone; and he does not dishonour him. There is no greater evil than that one should hold a Muslim in contempt." (Musnad Ahmad). Hadrat Sahl bin Sa'd as-Sa`idi has related this saying of the Holy Prophet: "A believer's relation with the community of the believers is just like the head's relation with the body. He feels their afflictions as the head feels the pain of every part of the body." (Musnad Ahmad). In another Hadith bearing on the same subject the Holy Prophet said: "The believers' example in the matter of their mutual love, relationship and compassion with one another is of the state of the body that when a part of it is afflicted the whole of it is afflicted with fever and restlessness." (Bukhari, Muslim). In another Hadith he is reported to have said: The believers are with one another like the bricks of a wall so that each is strengthened by the other. " (Bukhari: Kitab al-Adab; Tirmidhi; : Abwab al-Birr was-Silah).
