Narrated Ibn Abbas (
“Indeed, you are going to a nation from the People of the Scripture, so let the first thing to which you call them be the Oneness of Allah. If they learn that, tell them that Allah has enjoined on them five prayers to be offered in one day and one night. And if they pray, tell them that Allah has enjoined on them charity from their properties and it is to be taken from the rich among them and given to the poor. And if they agree to that, then take charity from them but avoid the best property of the people.”
[Sahih Bukhari, Volume 9, Book 93, Number 469]

ابْنَ عَبَّاسٍ، يَقُولُ لَمَّا بَعَثَ النَّبِيُّ صلى الله عليه وسلم مُعَاذًا نَحْوَ الْيَمَنِ قَالَ لَهُ ” إِنَّكَ تَقْدَمُ عَلَى قَوْمٍ مِنْ أَهْلِ الْكِتَابِ فَلْيَكُنْ أَوَّلَ مَا تَدْعُوهُمْ إِلَى أَنْ يُوَحِّدُوا اللَّهَ تَعَالَى فَإِذَا عَرَفُوا ذَلِكَ فَأَخْبِرْهُمْ أَنَّ اللَّهَ فَرَضَ عَلَيْهِمْ خَمْسَ صَلَوَاتٍ فِي يَوْمِهِمْ وَلَيْلَتِهِمْ، فَإِذَا صَلُّوا فَأَخْبِرْهُمْ أَنَّ اللَّهَ افْتَرَضَ عَلَيْهِمْ زَكَاةً فِي أَمْوَالِهِمْ تُؤْخَذُ مِنْ غَنِيِّهِمْ فَتُرَدُّ عَلَى فَقِيرِهِمْ، فَإِذَا أَقَرُّوا بِذَلِكَ فَخُذْ مِنْهُمْ وَتَوَقَّ كَرَائِمَ أَمْوَالِ النَّاسِ ”
