2يا أَيُّهَا الَّذينَ آمَنوا لا تَرفَعوا أَصواتَكُم فَوقَ صَوتِ النَّبِيِّ وَلا تَجهَروا لَهُ بِالقَولِ كَجَهرِ بَعضِكُم لِبَعضٍ أَن تَحبَطَ أَعمالُكُم وَأَنتُم لا تَشعُرونَAli UnalO you who believe! Do not raise your voices above the voice of the Prophet, nor speak loudly when addressing him, as you would speak loudly to one another, lest your good deeds go in vain without your perceiving it.1Obedience to the Messenger, upon him be peace and blessings, in all his verdicts means obedience to God, and faith in and obedience to God require unconditional obedience to the Messenger, upon him be peace and blessings. In addition, as any purposeful disrespect to him amounts to unbelief, it may cause one’s all good deeds to be in vain. This is so both during the Prophet’s life and after his death. There are some acts, though, that while they do not amount to unbelief in themselves, they carry the risk of causing unbelief. Raising one’s voice or any other action that does not arise from purposeful disrespect does not mean unbelief, yet it can cause the good deed done by way of speech or action to go in vain.
