The Noble Messenger of Allah [peace be upon him] said: " Whoever fulfilled the needs of his brother, Allah will fulfill his needs; whoever brought his brother out of a discomfort, Allah will bring him out of the discomforts of the Day of Resurrection"[Hadith- Bukhari]
There was once an elderly, sad woman in a nursing home. She wouldn't talk to anyone or request anything. She seemed merely to exist. Besides performing her daily prayers she would spend the rest of the day rocking in her creaky old rocking chair.
'Thank you,' she said. 'Thank you for rocking with me, it meant so much'
The Prophet Muhammad [peace be upon him] said, "A believer to another believer is like a building whose different parts enforce each other." The Prophet[pbuh] then clasped his hands with the fingers interlaced (while saying that). [Hadith- Bukhari]
