Allah Almighty says: {Indeed, in the creation of the heavens and earth and the alternation of the night and day are signs for people of understanding, those who remember Allah while standing, sitting, and lying on their sides} [Surat Āl ‘Imrān: 190-191]
1) The universal signs that Allah Almighty has made manifest in His creation call the wise to reflection and contemplation, and to use them as proof of the greatness of the Creator, for He alone is worthy of being worshiped, remembered, and thanked.
2) Those who remember Allah Almighty are the ones who have sound minds because they have understood the purpose behind the creation: {I have not created the jinn and mankind except to worship Me.}
1444/1- ‘Āishah (may Allah be pleased with her) reported: “The Prophet (may Allah’s peace and blessings be upon him) used to remember Allah Almighty at all times.” [Narrated by Muslim]
1) Remembering Allah Almighty is recommended and permissible at all times as suits the state of the slave, be he standing, sitting, lying down, and whether in a state of ritual purity or ritual impurity.
2) It is impermissible to recite Dhikr in dirty places or while answering the call of nature, because perfect glorification of Allah Almighty entails refraining from reciting Dhikr in such situations.
1445/2- Ibn ‘Abbās (may Allah be pleased with him and his father) reported that the Prophet (may Allah’s peace and blessings be upon him) said: “If anyone of you, before having sexual intercourse with his wife, says: Bismillah; Allahmumma jannibna ash-shaytān wa jannib ash-shaytān mā razaqtana (In the name of Allah; O Allah, protect us from Satan and protect what you bestow upon us from Satan), then if Allah decrees that they conceive a child as a result of this intimacy, Satan will not be able to harm him.” [Narrated by Al-Bukhāri and Muslim]
1) Firm adherence to remembering Allah Almighty is a means of protection from the devil.
2) It is recommended to mention Allah’s name and supplicate Him before engaging in sexual intercourse in order to get blessings and being protected from all evils.
