But if both lie and conceal (the defect of the goods), the blessing is erased from their transaction."

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates: The Prophet Muhammad (peace and blessings be upon him) passed by a heap of grain. He inserted his fingers into it and felt dampness. The Prophet (peace be upon him) said: O owner of this grain, what is this? He replied: O Messenger of Allah (peace be upon him)! Rain had fallen on it. The Prophet (peace be upon him) said: Why did you not put this (damp part) on top so that people could see it? Whoever deceives us is not from us.

I said: O Messenger of Allah (peace and blessings be upon him)! Who are those people? They will surely be ruined and will suffer loss. The Prophet (peace and blessings be upon him) repeated this statement, so I asked: Who are those people? The Prophet (peace and blessings be upon him) said: "The person who lets his lower garment hang (out of pride), the person who reminds others of his favors, and the person who sells his goods by swearing false oaths." (Imam Ibn Hibban, may Allah have mercy on him, says:) The statement of the Prophet (peace and blessings be upon him): "The one who lets it hang" refers to the person who lets his lower garment hang out of arrogance, and the statement of the Prophet (peace and blessings be upon him): "The one who reminds of favors" refers to the person who reminds others of his favor at the time of paying the obligatory zakat.

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Prophet Muhammad (peace and blessings be upon him) said: "There are three people with whom Allah will not speak, nor will He look at them with mercy.

The third is the person who forbids others from taking surplus water. Allah will say: Today I withhold My bounty from you, just as you withheld that surplus which was not the earning of your own hands."

Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) narrates: A Bedouin passed by with a goat. I said, "Will you sell this to me for three dirhams?" He said, "No, by Allah (I will not do so)." Then he sold me the goat. Later, I mentioned this matter to the Prophet (peace and blessings of Allah be upon him), so he (peace be upon him) said: "He has sold his Hereafter for his worldly life."

Sayyiduna Rifa’ah bin Rafi’ Ansari (may Allah be pleased with him) narrates: He went with the Prophet Muhammad (peace be upon him) towards Baqi’. People were buying and selling. The Prophet Muhammad (peace be upon him) called out in a loud voice:“O group of traders!”The people turned their attention towards him and began to look at him.

Sayyiduna Jabir (may Allah be pleased with him) narrates: We were coming from Makkah to Madinah.

The Noble Prophet (peace and blessings be upon him) said: No, you sell it to me. I replied: No, O Messenger of Allah (peace and blessings be upon him)! It is already yours. The Noble Prophet (peace and blessings be upon him) said: No, you sell it to me. I said: I owe a man one uqiyah of gold, so in exchange for that, it is yours. The Noble Prophet (peace and blessings be upon him) said: I have taken it; you ride it until you reach Madinah. When I reached Madinah, the Noble Prophet (peace and blessings be upon him) said to Sayyiduna Bilal (may Allah be pleased with him): Give him one uqiyah of gold and pay him extra.

That amount remained safe with me in a pouch, then at the incident of Harrah, the people of Shaam took it away.
