Asking Allah to have mercy on an unjust ruler and greeting a person who abandons Salah
Q 5: Is it permissible
to ask Allah (Exalted be He) to be merciful with unjust rulers or to initiate Salam (Islamic greeting of peace) with those who abandon Salah (Prayer)?
It is permissible to ask Allah (Exalted be He) to be merciful with unjust rulers so long as they died as Muslims.As regards a person who abandons Salah defiantly, they are regarded as Kafirs (disbelievers) according to Ijma` (consensus of scholars). Likewise, whoever abandons Salah out of laziness without denying its obligation is a Kafir according to the most correct opinion of the scholars. Hence, it is not permissible to initiate Salam with them or even to return their Salam, (Part No. 24; Page No. 142) because they are considered apostates.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
