Silsilah Sahihah

It is narrated from Sayyiduna Thawban (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "There will be some individuals from my Ummah that if they ask any of you for a dinar, he will not give it to them; if they ask for a dirham, he will not give it to them; and if they ask even for a fals (one-sixth of a dirham), he will not give it to them. But if they ask Allah Almighty for Paradise, He will grant them Paradise. These people are poor and destitute, they are considered insignificant (and unworthy of attention), but (in the sight of Allah Almighty, they are so valued that) if they swear an oath by Allah, He fulfills their oath."
