عن ابن مسعود أن رسول الله صلى الله عليه وسلم قال : ليس من عمل يقرب إلى الجنة إلا قد أمرتكم به ولا عمل يقرب إلى النار إلا قد نهيتكم عنه لا يستبطئن أحد منكم رزقه إن جبريل عليه السلام ألقى في روعي أن أحدا منكم لن يخرج من الدنيا حتى يستكمل رزقه فاتقوا الله أيها الناس وأجملوا في الطلب فإن استبطأ أحد منكم رزقه فلا يطلبه بمعصية الله فإن الله لا ينال فضله بمعصية (المستدرك للحاكم رقم 2136)

Hazrat Abdullah bin Mas’ood (radhiyallahu ‘anhu) reports that Rasulullah (sallallahu ‘alaihi wasallam) said, “There is no action that will draw you close to Jannah except that I have commanded you to carry it out, and there is no action that will draw you close to Jahannum except that I have prohibited you from perpetrating it. None of you should ever regard his sustenance to be delayed (as everything is destined to arrive at its time). Indeed Hazrat Jibreel (‘alaihis salaam) revealed wahi in my heart (from the side of Allah Ta‘ala) that none of you will leave the world until he receives his sustenance in full. Hence, fear Allah Ta‘ala, o people, and make your effort brief in seeking your livelihood (as everything that you will receive is predestined). If any of you regards his sustenance to be delayed then he should not seek it through an avenue whereby he will disobey Allah Ta‘ala, for indeed the grace (barakah in wealth) of Allah Ta‘ala cannot be acquired through engaging in sins.”
