عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ أَيُّهَا النَّاسُ إِنَّ اللَّهَ طَيِّبٌ لَا يَقْبَلُ إِلَّا طَيِّبًا وَإِنَّ اللَّهَ أَمَرَ الْمُؤْمِنِينَ بِمَا أَمَرَ بِهِ الْمُرْسَلِينَ فَقَالَ يَا أَيُّهَا الرُّسُلُ كُلُوا مِنَ الطَّيِّبَاتِ وَاعْمَلُوا صَالِحًا إِنِّي بِمَا تَعْمَلُونَ عَلِيمٌ وَقَالَ يَا أَيُّهَا الَّذِينَ آمَنُوا كُلُوا مِنْ طَيِّبَاتِ مَا رَزَقْنَاكُمْ ثُمَّ ذَكَرَ الرَّجُلَ يُطِيلُ السَّفَرَ أَشْعَثَ أَغْبَرَ ثُمَّ يَمُدُّ يَدَيْهِ إِلَى السَّمَاءِ يَا رَبِّ يَا رَبِّ وَمَطْعَمُهُ حَرَامٌ وَمَشْرَبُهُ حَرَامٌ وَمَلْبَسُهُ حَرَامٌ وَغُذِّيَ بِالْحَرَامِ فَأَنَّى يُسْتَجَابُ لِذَلِكَ
It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: O people! Allah Almighty is pure and accepts only that which is pure, and indeed Allah Almighty has commanded the believers with the same command that He gave to His messengers. Allah the Exalted says: O Messengers! Eat of the pure things and do righteous deeds; surely I am aware of what you do. (: Surah Al-Mu’minun: 51) And He also said: O believers! Eat of the pure things which We have provided for you as sustenance. (: Surah Al-Baqarah: 172) Then the Prophet (peace and blessings be upon him) mentioned a man who undertakes a long journey, his hair is disheveled and covered with dust, and he stretches his hands towards the sky and supplicates: O my Lord! O my Lord! While his food, drink, clothing, and nourishment are unlawful, so how can his supplication be accepted?
