To be friendly/cordial to the requester

۞ قَوْلٌۭ مَّعْرُوفٌۭ وَمَغْفِرَةٌ خَيْرٌۭ مِّن صَدَقَةٍۢ يَتْبَعُهَآ أَذًۭى ۗ وَٱللَّهُ غَنِىٌّ حَلِيمٌۭ

Kind words and the covering of faults are better than charity followed by injury. Allah is free of all wants, and He is Most-Forbearing.

وَإِمَّا تُعْرِضَنَّ عَنْهُمُ ٱبْتِغَآءَ رَحْمَةٍۢ مِّن رَّبِّكَ تَرْجُوهَا فَقُل لَّهُمْ قَوْلًۭا مَّيْسُورًۭا

And even if thou hast to turn away from them in pursuit of the Mercy from thy Lord which thou dost expect, yet speak to them a word of easy kindness.
