Ibn Umar (Allah be pleased with them) said that Allah's Messenger (may peace be upon him) prohibited Shighar which means that a man gives his daughter in marriage on the condition that the other gives his daughter to him in marriage with- out any dower being paid by either.

Allah's Apostle forbade Ash-Shighar, which means that somebody marries his daughter to somebody else, and the latter marries his daughter to the former without paying Mahr.

Yahya related to me from Malik from Nafi from Abdullah ibn Umar that the Messenger of Allah, may Allah bless him and grant him peace, forbade shighar, which meant one man giving his daughter in marriage to another man on the condition that the other gave his daughter to him in marriage without either of them paying the bride-price.

Nafi narrated to me that 'Abdullah said that Allah's Apostle forbade the Shighar. I asked Nafi', "What is the Shighar?" He said, "It is to marry the daughter of a man and marry one's daughter to that man (at the same time) without Mahr (in both cases); or to marry the sister of a man and marry one's own sister to that man without Mahr." Some people said, "If one, by a trick, marries on the basis of Shighar, the marriage is valid but its condition is illegal." The same scholar said regarding Al-Mut'a, "The marriage is invalid and its condition is illegal." Some others said, "The Mut'a and the Shighar are permissible but the condition is illegal."

Ibn Umar (Allah be pleased with them) reported that Allah's Messenger (may peace be upon him) prohibited Shighar.

Jabir b. Abdullah (Allah be pleased with him) reported that Allah's Messenger (may peace be upon him) prohibited Shighar.

Jabir reported that Allah's Messenger (may peace be upon him) forbade the wrapping of oneself completely leaving no room for the arm and supporting oneself when sitting with a single garment wrapped round one's knees and a person raising one of his feet and placing it on the other while lying on his back.

Allah's Apostle forbade two ways of wearing clothes and two kinds of dealings. (A) He forbade the dealings of the Mulamasa and the Munabadha. In the Mulamasa transaction the buyer just touches the garment he wants to buy at night or by daytime, and that touch would oblige him to buy it. In the Munabadha, one man throws his garment at another and the latter throws his at the former and the barter is complete and valid without examining the two objects or being satisfied with them (B) The two ways of wearing clothes were Ishtimal-as-Samma, i e., to cover one's shoulder with one's garment and leave the other bare: and the other way was to wrap oneself with a garment while one was sitting in such a way that nothing of that garment would cover one's private part.

(regarding His Statement): 'They ask your instruction concerning the women. Say: Allah instructs you about them ...' (4.127) It is about the female orphan who is under the guardianship of a man with whom she shares her property and he does not want to marry her and dislikes that someone else should marry her, lest he should share the property with him, so he prevents her from marrying. So Allah forbade such a guardian to do so (i.e. to prevent her from marrying).

Regarding the Verse:--"They ask your instruction concerning the women. Say: Allah instructs you about them and yet whom you desire to marry." (4.127) (has been revealed regarding the case of) a man who has an orphan girl, and he is her guardian and her heir. The girl shares with him all his property, even a date-palm (garden), but he desires to marry her and dislikes to give her in marriage to somebody else who would share with him the property she is sharing with him, and for this reason that guardian prevents that orphan girl from marrying. So, this Verse was revealed.

The Messenger of Allah (saws) prohibited, according to the version of Ahmad ibn Hanbal, that a person should sit during prayer while he is leaning on his hand.

According to the version of Ibn Shibwayh, he prohibited that a man should lean on his hand during prayer.

According to the version of Ibn Rafi', he prohibited that a man should pray while he is leaning on his hand, and he mentioned this tradition in the chapter on "Raising the head after prostration."

According to the version of Ibn AbdulMalik, he prohibited that a man should lean on his hand when he stands up after prostration.

Abu Huraira (Allah be pleased with him) reported that Allah's Messenger (may peace be upon him) forbade the (people) meeting the caravan (for entering into business transaction with them), and the selling of goods by a townsman on behalf of a man of the desert, and seeking by a woman the divorce of her sister (from her husband), and outbidding (against one another), and tying up the udders (of animals), and buying of (things) in opposition to one's brother.

Regarding the Qur'anic Verse: 'O you who believe! You are forbidden to inherit women against their will.' (4.19) The custom (in the Pre-lslamic Period) was that if a man died, his relatives used to have the right to inherit his wife, and if one of them wished, he could marry her, or they could marry her to somebody else, or prevent her from marrying if they wished, for they had more right to dispose of her than her own relatives. Therefore this Verse was revealed concerning this matter.
