Hafiz Abdush Shakoor Tirmidhi
Benefits:
➊ From the mentioned hadith, it is understood that one should not conduct a sale over another’s sale. This is in the manner that two people have finalized a transaction and have given an option that for a certain number of days, you have the choice to return it or keep it, or similarly, the seller says that if I wish, I can take the item back from you within a certain number of days. Then, another person comes to the buyer and says, “Return this item, I will give you a better one than this,” or, “I will give you a similar item for a cheaper price,” or similarly, he says to the owner, “Take your item back, and I will buy it from you for a higher price.” This is not permissible.
Hafiz Ibn Hajar rahimahullah states that there is no difference of opinion regarding its prohibition. (Fath al-Bari: 5/88)
➋ ... It is understood that proposing over someone else’s proposal (engagement) is forbidden. This is in the case where a man sends a marriage proposal to a household, and both families agree, with only the marriage contract (nikah) remaining, then another man sends a proposal and says, “Leave the previous proposal and marry me.” Doing so is prohibited. The second man is only permitted to send a proposal if the first man withdraws his proposal or gives permission, as is mentioned in the hadith: ((حَتَّی یَتْرُكَ الْخَاطِبُ قَبْلَهٗ اَوْ یَاْذَنَ لَهٗ الْخَاطِبُ)) (Bukhari, Kitab al-Nikah, No: 5142) ... “Until the one who sent the proposal before him withdraws his intention, or gives him permission to send a proposal, then it is permissible.”
Imam Nawawi rahimahullah, in his commentary on the mentioned hadith, states: This (hadith and all such) ahadith indicate the prohibition of proposing over the proposal of one’s brother. (Sharh Muslim, by al-Nawawi: 5/214)
➌ ... No woman should demand the divorce of her Muslim sister. There are two forms of this, which are as follows: 1. That a man wishes to marry a woman, and the woman says, “Divorce your first wife, then I will marry you.” In doing so, she is violating the rights of the first wife. 2. The second is that a woman demands the divorce of her co-wife, with the intention that the facilities and expenses provided by the husband to the co-wife should also come to her. Doing so is also forbidden.
