The sayings of Prophet Muhammad peace be upon him

[أبوسيف]

Fiqh-us-Sunnah Fiqh 3.101a
The Messenger of Allah (saws)] mentioned a man who had traveled for a long time. Unkempt and covered in dust, he raised his hands to the heavens (and cried):
`O my Lord…..! O my Lord……!` His food was unlawful, his drink was unlawful, his clothing was unlawful, and what he had provided to sustain himself with was also unlawful. How could his invocation be accepted?"

عن أبي هريرة قال قال رسول الله صلى الله عليه وسلم : (أيها الناس إن الله طيب لا يقبل إلا طيبا وإن الله أمر المؤمنين بما أمر به المرسلين فقال يا أيها الرسل كلوا من الطيبات واعملوا صالحا إني بما تعملون عليم وقال يا أيها الذين آمنوا كلوا من طيبات ما رزقناكم ثم ذكر الرجل يطيل السفر أشعث أغبر يمد يديه إلى السماء يا رب يا رب ومطعمه حرام ومشربه حرام وملبسه حرام وغذي بالحرام فأنى يستجاب لذلك).
