All perfect praise be to Allah, the Lord of the worlds. I testify that there is none worthy of worship except Allah and that Muhammad is His slave and Messenger.
This hadeeth, like other ahaadeeth about the Attributes of Allah, is subject to the established rule by Ahlus-Sunnah wal Jamaa‘ah: “Let it be (leave it) as it is without asking how.”
Shaykh ‘Alawi As-Saqqaaf quoted the response of Shaykh Ibn Taymiyyah to Ar-Raazi when he (Ar-Raazi) interpreted this hadeeth metaphorically to mean that the Prophet found the effect of Divine Care (in a way other than its literal meaning).
Shaykh 'Alawi, in his book The Attributes of Allah in the Quran and the Sunnah (pp. 524-526), said:
“Shaykh Ibn Taymiyyah said in Naqdh Asaas At-Taqdees about the statement of Ar-Raazi, ‘I found the coolness of his fingers, i.e. I found the effect of that (Divine) Care.’ As a response to him, we say: the effect of that Care was felt on his back, his heart, and his chest, so restricting the meaning to be the effect of Divine Care is not permissible… The statement: ‘He put his hand between my shoulders until I found the coolness of His Fingers between my breasts,’ does not allow the probability of interpreting it in other than its literal meaning by saying that it means mere care. This [interpreting it in this manner] is known to be invalid in the Arabic language.”
Allah knows best.
