رقب

رُقْبَى ذ One's giving to another person a possession, (K,) such as a house, and land, and the like, (TA,) on the condition that, whichever of them shall die, the property shall revert to his [ the giver's ] heirs: (K:) so called because each of them looks for (يَرْقُبُ) the death of the other: (TA:) or one's assigning it, (K,) namely, a dwelling, (TA,) to another person to inhabit, and, when he shall die, to another: (K:) or one's saying to a man, If thou die before me, my dwelling [or my land, which I give to thee, ] shall revert to me; and if I die before thee, it shall be thine: so called for the reason above mentioned. (JK, KT. *) [It also signifies The property so given. ] See 4, in three places. The act thus termed is forbidden in a trad., which pronounces that the property so given belongs to the giver's heirs. (JK.) Accord. to the Imám Aboo-Haneefeh, and [the Imám] Mohammad, it is not a هِبَة: accord. to Aboo-Yoosuf, it is a هِبَة like the عُمْرَى; but none of the lawyers of El- 'Irák says so: the Málikees absolutely forbid it. (TA.) You say, دَارِى لَكَ رُقْبَى [ My house is thine as a رقبى]: from المُرَاقَبَةُ; because each of the two persons looks for the death of the other. (A.)
