how shall a muslim practice daawa in times of calamities meaning in revolutions and disorder

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.

Da’wah (calling people to Allaah) during such days is like Da’wah at any other days where the general etiquettes of Da’wah should be met; we have indeed discussed some of them in Fataawa 21186, 84348 and 7583.

However, it should be added here that a Muslim should be reminded of protecting the blood of his fellow Muslim, as there are many Ahaadeeth in this regard among which is the saying of the Prophet : ''All things of a Muslim are sacred (inviolable) for his Muslim brother: his blood, his wealth and his honor.” [Al-Bukhari and Muslim]; and the saying of the Prophet : ''The property of a Muslim is not lawful (for anyone) except with his consent.” [Ahmad and Abu Daawood]

Similarly, the public and private property should be safeguarded as it is sacred and it is not permissible to transgress it without right; the previous Ahaadeeth also confirm this.

Allaah Knows best.
