Prophet Mohammad - Abu-Masud: Bukhari

If you do not feel ashamed of anything, then you can do whatever you like.
Prophet Mohammad
What actions are most excellent? To gladden the heart of human beings, to feed the hungry, to help the afflicted, to lighten the sorrow of the sorrowful, and to remove the sufferings of the injured.
Prophet Mohammad - Bukhari & Muslim
When two persons are together, two of them must no whisper to each other, without letting the third hear; because it would hurt him.
