أسباب إجابة الدعاء وموانعه
Abu Hurayrah (may Allah be pleased with him) reported: The Prophet (may Allah's peace and blessings be upon him) said: "Indeed, Allah is good and accepts only what is good. And Allah commanded the believers as He commanded the Messengers. He says: {Indeed, I am All-Knowing of what you do.} [Sūrat al-Mu'minūn: 51] And He says: {O you who believe, eat from the good things which We have provided for you.} [Sūrat al-Baqarah: 172]" He then mentioned a person who travels for so long that his hair is disheveled and covered with dust. He lifts his hand toward the sky (saying): ‘O Lord, O Lord,’ but his food is unlawful, his drinks are unlawful, and his clothing is unlawful, and he has been nourished by the unlawful. So how can his supplication be accepted?"  
عن أبي هريرة -رضي الله عنه- عن النبي -صلى الله عليه وسلم- قال: إِنَّ اللهَ طَيِّبٌ لَا يَقْبَلُ إِلَّا طَيِّبًا، وَإِنَّ اللهَ أَمَرَ الْمُؤْمِنِينَ بِمَا أَمَرَ بِهِ الْمُرْسَلِينَ، فَقَالَ: {يَا أَيُّهَا الرُّسُلُ كُلُوا مِنَ الطَّيِّبَاتِ وَاعْمَلُوا صَالِحًا، إِنِّي بِمَا تَعْمَلُونَ عَلِيمٌ} [المؤمنون: 51] وَقَالَ: {يَا أَيُّهَا الَّذِينَ آمَنُوا كُلُوا مِنْ طَيِّبَاتِ مَا رَزَقْنَاكُمْ} [البقرة: 172] ثُمَّ ذَكَرَ الرَّجُلَ يُطِيلُ السَّفَرَ أَشْعَثَ أَغْبَرَ، يَمُدُّ يَدَيْهِ إِلَى السَّمَاءِ، يَا رَبِّ، يَا رَبِّ، وَمَطْعَمُهُ حَرَامٌ، وَمَشْرَبُهُ حَرَامٌ، وَمَلْبَسُهُ حَرَامٌ، وَغُذِيَ بِالْحَرَامِ، فَأَنَّى يُسْتَجَابُ لِذَلِكَ؟.

شرح الحديث :


Allah, the Almighty, is far exalted above defects and imperfections. He possesses all the attributes of majesty, excellence, and perfection. So no slave should try to draw close to Him by means of giving charity from ill-gotten or suspicious sources, or through donating inferior quality food. Allah commanded the believers to eat good food just as He had commanded the messengers, and this should be accompanied by good deeds and gratitude to the Almighty Lord for His favors. The Prophet (may Allah's peace and blessings be upon him) then demonstrated that, just as Allah, the Almighty, only likes charity from good and lawful sources, He also only likes good deeds, and they can only be good through sincerity and following the prophetic Sunnah. The Prophet (may Allah's peace and blessings be upon him) then gave an example as a warning to His Ummah against unlawful earning. He mentioned a man who travels for so long, for righteous purposes, such as Hajj, Jihad, or to earn an income. The man has a disheveled hair and is covered in dust due to his long journey for a good purpose. He raises his hands toward the sky supplicating to Allah, imploring Him, and standing humbly before Him. Nonetheless, his supplication is unlikely to be answered due to his illicit earnings, and as all his food and drink were unlawful.
