عن بن عباس قال تليت هذه الآية عند رسول الله صلى الله عليه و سلم ( يا أيها الناس كلوا مما في الأرض حلالا طيبا ) فقام سعد بن أبي وقاص فقال يارسول الله ادع الله أن يجعلني مستجاب الدعوة فقال له النبي صلى الله عليه و سلم يا سعد أطب مطعمك
تكن مستجاب الدعوة والذي نفس محمد بيده إن العبد ليقذف اللقمة الحرام في جوفه ما يتقبل منه عمل أربعين يوما وأيما عبد نبت لحمه من السحت والربا فالنار أولى به۔ (المعجم الأوسط:6/ 310، مجمع الزوائد:4/ 143)
It has been narrated on the authority of Hazrat Ibn-e-Abbaas (May Allah be pleased with both of them) that once the Aayah يا أيها الناس كلوا مما في الأرض حلالا طيبا was recited
in the presence of the Holy Prophetصلی اللہ علیہ وسلم. Thereupon, Hazrat Sa’ad Bin Abi Waqaas (May Allah be pleased with him) stood up and said, “O prophet of Allah, pray to Allah to make me Mustajaab-ud-D’awaat (i.e. the one whose prayers are granted).” The Holy Prophet said to him, “O Sa’ad, make your food Tayyib, (and as a result) you will Mustajaab-ud-D’awaat. I swear by the ONE in whose possession is Muhammad’s soul that whenever a man puts a Haraam morsel into his stomach, no (good) deed of his is accepted for forty days; and that fire (of the Hell) deserves the one who is fed on haram and Riba more (i.e. It is more befitting for such a person to enter the Hell).”
Brief Commentary and Interpretation:
The greatest benefit of halal is that due to making efforts for Halaal livelihood, worship and prayers are accepted. When Hazrat Sa’ad Bin Abi Waqaas (May Allah be pleased with him) acted upon the instructions given to him by the Holy Prophetصلی اللہ علیہ وسلم, Allah Ta’ala made him Mustajaab-ud-D’awaat. Hence once he was asked, “Among the Sahaabah (i.e. Companions of the Holy Prophetصلی اللہ علیہ وسلم) your prayers are (specially) granted. What is the reason for that?” “I don’t put into my mouth a morsel unless I confirm where it has come from” was his reply. In fact, he meant that first he used to satisfy himself that it was Halaal, and then he would eat it.
