some of the desert dwelling arabs believe in god and the day of judgment. whatever they spend for the cause of god they consider it as a means of getting nearer to god and have the prayers of the messenger in their favor. this certainly is a means to get nearer to god. god will admit them into his mercy. god is allforgiving and allmerciful.
ومن الأعراب من يؤمن بالله واليوم الآخر ويتخذ ما ينفق قربات عند الله وصلوات الرسول ألا إنها قربة لهم سيدخلهم الله في رحمته إن الله غفور رحيم
