Jadikanlah materi dakwah pertamamu adalah mentauhidkan Allah
Imam Bukhari : 1308حَدَّثَنَا أَبُو عَاصِمٍ الضَّحَّاكُ بْنُ مَخْلَدٍ عَنْ زَكَرِيَّاءَ بْنِ إِسْحَاقَ عَنْ يَحْيَى بْنِ عَبْدِ اللَّهِ بْنِ صَيْفِيٍّ عَنْ أَبِي مَعْبَدٍ عَنْ ابْنِ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُمَاأَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بَعَثَ مُعَاذًا رَضِيَ اللَّهُ عَنْهُ إِلَى الْيَمَنِ فَقَالَ ادْعُهُمْ إِلَى شَهَادَةِ أَنْ لَا إِلَهَ إِلَّا اللَّهُ وَأَنِّي رَسُولُ اللَّهِ فَإِنْ هُمْ أَطَاعُوا لِذَلِكَ فَأَعْلِمْهُمْ أَنَّ اللَّهَ قَدْ افْتَرَضَ عَلَيْهِمْ خَمْسَ صَلَوَاتٍ فِي كُلِّ يَوْمٍ وَلَيْلَةٍ فَإِنْ هُمْ أَطَاعُوا لِذَلِكَ فَأَعْلِمْهُمْ أَنَّ اللَّهَ افْتَرَضَ عَلَيْهِمْ صَدَقَةً فِي أَمْوَالِهِمْ تُؤْخَذُ مِنْ أَغْنِيَائِهِمْ وَتُرَدُّ عَلَى فُقَرَائِهِمْ
Narrated by Abu 'Asim Adh-Dhahhak bin Makhlad, from Zakariyya bin Ishaq, from Yahya bin 'Abdullah bin Shayfiy, from Abu Ma?bad, from Ibn 'Abbas (may Allah be pleased with them), that when the Prophet (peace and blessings be upon him) sent Mu?adh (may Allah be pleased with him) to Yemen, he said: 'Invite them to testify that there is no god but Allah and that I am the Messenger of Allah. If they obey, inform them that Allah has made obligatory upon them five prayers every day and night. If they obey, inform them that Allah has made obligatory upon them charity (zakat) from their wealth, taken from their rich and given to their poor.'
