52:40
أَمْ تَسْـَٔلُهُمْ أَجْرًا فَهُم مِّن مَّغْرَمٍ مُّثْقَلُونَ
am tasaluhum ajran fahum min maghramin muth'qalūna
Do you [Prophet] demand a payment from them that would burden them with debt?
Or is it that you (O Muhammad صلى الله عليه وسلم) ask a wage from them (for your preaching of Islâmic Monotheism) so that they are burdened with a load of debt?
