The Da’iyah (Islamic Missioner) who fears Allah’s Punishment upon his people should keep calling his people to worship Allah and should remind them continuously of Almighty the Almighty until Allah establishes what he has decreed.
“And the man who believed urged, “O my people! Follow me, ˹and˺ I will lead you to the Way of Guidance* O my people! This worldly life is only ˹a fleeting˺ enjoyment, whereas the Hereafter is truly the home of settlement* Whoever does an evil deed will only be paid back with its equivalent. And whoever does good, whether male or female and is a believer, they will enter Paradise, where they will be provided for without limit* O my people! How is it that I invite you to salvation, while you invite me to the Fire?* You invite me to disbelieve in Allah and associate with Him what I have no knowledge of, while I invite you to the Almighty, Most Forgiving* There is no doubt that whatever ˹idols˺ you invite me to ˹worship˺ are not worthy to be invoked either in this world or the Hereafter.1 ˹Undoubtedly,˺ our return is to Allah, and the transgressors will be the inmates of the Fire*You will remember what I say to you, and I entrust my affairs to Allah. Surely Allah is All-Seeing of all ˹His˺ servants.” (Ghafir 40: 38-44)
أن على الداعية الذي يخاف على قومه من بأس الله عز وجل أن يستمر في دعوة قومه وتذكيرهم بالله عز وجل حتى يقضي الله أمره
وَقَالَ الَّذِي آمَنَ يَا قَوْمِ اتَّبِعُونِ أَهْدِكُمْ سَبِيلَ الرَّشَادِ. يَا قَوْمِ إِنَّمَا هَذِهِ الْحَيَاةُ الدُّنْيَا مَتَاعٌ وَإِنَّ الْآخِرَةَ هِيَ دَارُ الْقَرَارِ. مَنْ عَمِلَ سَيِّئَةً فَلَا يُجْزَى إِلَّا مِثْلَهَا وَمَنْ عَمِلَ صَالِحًا مِنْ ذَكَرٍ أَوْ أُنْثَى وَهُوَ مُؤْمِنٌ فَأُولَئِكَ يَدْخُلُونَ الْجَنَّةَ يُرْزَقُونَ فِيهَا بِغَيْرِ حِسَابٍ. وَيَا قَوْمِ مَا لِي أَدْعُوكُمْ إِلَى النَّجَاةِ وَتَدْعُونَنِي إِلَى النَّارِ. تَدْعُونَنِي لِأَكْفُرَ بِاللَّهِ وَأُشْرِكَ بِهِ مَا لَيْسَ لِي بِهِ عِلْمٌ وَأَنَا أَدْعُوكُمْ إِلَى الْعَزِيزِ الْغَفَّارِ. لَا جَرَمَ أَنَّمَا تَدْعُونَنِي إِلَيْهِ لَيْسَ لَهُ دَعْوَةٌ فِي الدُّنْيَا وَلَا فِي الْآخِرَةِ وَأَنَّ مَرَدَّنَا إِلَى اللَّهِ وَأَنَّ الْمُسْرِفِينَ هُمْ أَصْحَابُ النَّارِ. فَسَتَذْكُرُونَ مَا أَقُولُ لَكُمْ وَأُفَوِّضُ أَمْرِي إِلَى اللَّهِ إِنَّ اللَّهَ بَصِيرٌ بِالْعِبَادِ ” (غافر 40: 38-44)
