2 Preface يا أَيُّهَا الَّذينَ آمَنوا لا تَرفَعوا أَصواتَكُم فَوقَ صَوتِ النَّبِيِّ وَلا تَجهَروا لَهُ بِالقَولِ كَجَهرِ بَعضِكُم لِبَعضٍ أَن تَحبَطَ أَعمالُكُم وَأَنتُم لا تَشعُرونَAli Quli QaraiO you who have faith! Do not raise your voices above the voice of the Prophet, and do not speak aloud to him as you shout to one another, lest your works should fail without your being aware.
