Question : The question says: When the Prophet (peace and blessings be upon him) asked Mu'adh, "Do you know what is the right of Allah upon His servants?" he said:
Answer : No, there is nothing wrong with that. Even when Jabir said, "Sell it to me for a small amount, sell me the camel?" he said, "No, there is nothing in that." But he says that people nowadays say "Salamatak" instead of "Salamah." If people consider this to be a lack of proper conduct, there is no harm in saying "Salamatak."
