Tafsir of Al-Mu'minoon 23:98

"And I seek refuge with You, My Lord! lest they should come near me.'' means, in any issue of my life. So we are commanded to mention Allah at the beginning of any undertaking, in order to ward off the Shayatin at the time of eating, intercourse, slaughtering animals for food, etc. Abu Dawud recorded that the Messenger of Allah used to say:

اللهم

إني أعوذ بك من الهرم

وأعوذ بك من الهدم ومن الغرق

وأعوذ بك من أن يتخبطني الشيطان عند الموت

O Allah, I seek refuge with You from old age, I seek refuge with You from being crushed or drowned, and I seek refuge with you from being assaulted by the Shayatin at the time of death
