Sahih al-Bukhari 4347
Narrated Ibn `Abbas:
Allah's Messenger (ﷺ) said to Mu`adh bin Jabal when he sent him to Yemen. "You will come to the people of 
Scripture, and when you reach them, invite them to testify that none has the right to be worshipped 
except Allah and that Muhammad is His Apostle. And if they obey you in that, then tell them that 
Allah has enjoined on them five prayers to be performed every day and night. And if they obey you in 
that, then tell them that Allah has enjoined on them Sadaqa (i.e. rak`at) to be taken from the rich 
amongst them and given to the poor amongst them. And if they obey you in that, then be cautious! 
Don't take their best properties (as Zakat) and be afraid of the curse of an oppressed person as there is 
no screen between his invocation and Allah.
حَدَّثَنِي حِبَّانُ، أَخْبَرَنَا عَبْدُ اللَّهِ، عَنْ زَكَرِيَّاءَ بْنِ إِسْحَاقَ، عَنْ يَحْيَى بْنِ عَبْدِ اللَّهِ بْنِ صَيْفِيٍّ، عَنْ أَبِي مَعْبَدٍ، مَوْلَى ابْنِ عَبَّاسٍ عَنِ ابْنِ عَبَّاسٍ ـ رضى الله عنهما ـ قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم لِمُعَاذِ بْنِ جَبَلٍ حِينَ بَعَثَهُ إِلَى الْيَمَنِ ‏
"‏ إِنَّكَ سَتَأْتِي قَوْمًا مِنْ أَهْلِ الْكِتَابِ، فَإِذَا جِئْتَهُمْ فَادْعُهُمْ إِلَى أَنْ يَشْهَدُوا أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ، وَأَنَّ مُحَمَّدًا رَسُولُ اللَّهِ، فَإِنْ هُمْ طَاعُوا لَكَ بِذَلِكَ فَأَخْبِرْهُمْ أَنَّ اللَّهَ قَدْ فَرَضَ عَلَيْهِمْ خَمْسَ صَلَوَاتٍ فِي كُلِّ يَوْمٍ وَلَيْلَةٍ، فَإِنْ هُمْ طَاعُوا لَكَ بِذَلِكَ، فَأَخْبِرْهُمْ أَنَّ اللَّهَ قَدْ فَرَضَ عَلَيْكُمْ صَدَقَةً، تُؤْخَذُ مِنْ أَغْنِيَائِهِمْ، فَتُرَدُّ عَلَى فُقَرَائِهِمْ، فَإِنْ هُمْ طَاعُوا لَكَ بِذَلِكَ، فَإِيَّاكَ وَكَرَائِمَ أَمْوَالِهِمْ، وَاتَّقِ دَعْوَةَ الْمَظْلُومِ فَإِنَّهُ لَيْسَ بَيْنَهُ وَبَيْنَ اللَّهِ حِجَابٌ ‏"‏‏.‏ قَالَ أَبُو عَبْدِ اللَّهِ ‏{‏طَوَّعَتْ‏}‏ طَاعَتْ وَأَطَاعَتْ لُغَةٌ، طِعْتُ وَطُعْتُ وَأَطَعْتُ‏.‏
