The next stage in the process of human development is qararin makin. The word qararin means to make sedentary, to establish, to assign, to schedule, to determine, to stipulate, to regulate and to decide; and it carries the further meanings of to confirm, to establish and to affirm.45 The word makin has meanings that include to place, to put/set down firmly and to put in position.46 The combination of these two words provide connotations of: in a safe place, in a place firmly fixed, in a safe lodging and in a firm resting place.

The terms used by the Qur’an at this stage coincide with modern embryology. The zygote divides into a ball of cells with an outer shell to form the blastocyst. Studies in embryology assert that around the 6th day after fertilization the blastocyst implants itself securely into the uterine wall. Embryologists John Allen and Beverley Kramer explain the process of implantation:

Dasawa a kusa da rana ta 6 zuwa ta 7 bayan hadi ne dasawa (implantation) ke farawa. Ɓangaren blastocyst da ke fitowa cikin ramin mahaifa yana ci gaba da kasancewa sirara sosai. Syntrophoblast yana ɗauke da wani enzyme mai narkar da protein wanda ke haifar da lalacewar ƙwayoyin endometrium, ta yadda blastocyst ɗin zai ci gaba da nutsewa zurfi da zurfi cikin mucosa na mahaifa… Ragowar gibin da ke cikin endometrium ana rufe shi da wani gudan jini ko fibrin, wanda ke lulluɓe blastocyst ɗin. Wannan murfi ana kiransa operculum. Kusan kwanaki 10 zuwa 12 bayan hadi, blastocyst ɗin ya lulluɓu gaba ɗaya a cikin endometrium, kuma haka dasawa ta cika.47

Implantation begins at about the 6th to 7th day after fertilization. The part of the blastocyst projecting into the uterine cavity remains relatively thin. The syntrophoblast contains a proteolytic enzyme which causes destruction of the endometrial cells so that that the blastocyst sinks deeper and deeper into the uterine mucosa…The final deficiency in the endometrium is sealed off by a blood or fibrin clot, overlying the blastocyst. This cover is called the operculum. By about 10 to 12 days after fertilization, the blastocyst is completely encased in the endometrium and thus, implantation is complete.47

Nazarin kalmomin qararin makin, ya nuna ci gaban zamani a ilimin tayin (embryology). Ma'anonin da haɗin kalmomin qararin makin ya bayar sun nuna cewa blastocyst yana nutsewa "zurfi da zurfi", da kuma cewa endometrium yana rufewa da "fibrin clot", domin tabbatar da cewa blastocyst "an lulluɓe shi gaba ɗaya".

The analysis of the words qararin makin, reflect modern developments in embryology. The meanings offered by the combination of the words qararin makin depict the blastocyst sinking ‘deeper and deeper’ and the sealing off of the endometrium with a ‘fibrin clot’ ensuring the blastocyst is ‘completely encased’.

Matakin qararin makin: Blastocyst din yana nutsewa cikin endometrium, har a lullube shi gaba daya, watau tsarin dasawa (implantation).

The qararin makin stage: The blastocyst sinking in the endomentrium, being completely encased i.e. the process of implantation.
