People's inner reality is not what you observe. If performed, you will deeply regret it.

There is no Khayr (goodness) in this transaction. Do not do it.
وَلِكُلٍّ دَرَجَاتٌ مِّمَّا عَمِلُوا ۚ وَمَا رَبُّكَ بِغَافِلٍ عَمَّا يَعْمَلُونَ
Walikullin darajatun mimma AAamiloo wama rabbuka bighafilin AAamma yaAAmaloona
To all are degrees (or ranks) according to their deeds: for thy Lord is not unmindful of anything that they do.
