Only Allah Who Knows the Nature of the Soul
In the first place, we’d like to make it clear that the Qur’an instructs us that the ruh (soul) is something known only to Allah. Bearing this in mind, a Muslim should concentrate on what brings him spiritual fulfillment. When the Prophet (peace and blessings be upon him) was asked about the nature of the soul, Almighty Allah instructed him to answer them in plain words: “They will ask thee concerning the soul. Say: The soul is by command of my Lord, and of knowledge ye have been vouchsafed but little” (Al-Israa‘: 85).
Answering the question, sheikh `Abdel Khaliq Hasan Ash-Shareef, said,
“Brothers in Islam, the answer of this question is based on knowing the true nature of the soul which is beyond our knowledge. Allah says, “They are asking thee concerning the Spirit. Say: The Spirit is by command of my Lord, and of knowledge ye have been vouchsafed but little.” (Surah Al-Isra’, 17:85)
as long as we do not know the essence of the soul, we’d not be able to know that. Moreover, the verse does not mean that the soul is with Allah over the throne.”
