Protect your child

Narrated Ibn Abbas:

The Prophet said, “If anyone of you, when having sexual intercourse with his wife, says:
Bismillah, Allahumma jannibna-Sh-Shaitan wa jannib-ish-Shaitan ma razaqtana,
and if it is destined that they should have a child, then Satan will never be able to harm him.” [Bukhari]

Dua before making love

بِسْمِ اللَّهِ . اللَّهُمَّ جَنِّبْنَا الشَّيْطَانَ ، وَ جَنِّبِ الشِّيْطَانَ مَا رَزَقْتَنَا

Bismillah. Allahumma jannibnash-shaytan. Wa jannibish-shaytana-ma razaqtana.

‘With the name of Allah! O Allah! Save us from the evil of Shaytan and save whatever children You bestow us.’
[Maariful Hadeeth]

Beneficial Knowledge

Beneficial knowledge is [knowledge] that increases your fear of God Most High, improves your ability to discern the faults of your ego, makes you more cognizant of how to worship your Lord, reduces your desire for this world, increases your longing for the next world, and opens your spiritual insight to the disastrous defects of your actions so you can avoid them. It discloses to you the plots and delusions of the Devil and how he misleads the scholars who have gone astray until he exposes them to the hatred and anger of God Most High, for they have used religion to purchase this world, taken knowledge as a means to gain the wealth of sultans, to consume the wealth of religious endowments, the poor, and the needy, and turned their energies throughout the day to the acquisition of prestige and high standing in the hearts of people, which forces them to show off their good deeds, to argue, and to be quarrelsome and ostentatious when they speak.
Imam Ghazali, Bidayat al-Hidaya
