Hazrat Shaikh Moulana Muhammad Zakariyya (rahmatullahi ‘alaih) once mentioned the following to a person who mentioned that his wife had missed her salaah on account of being busy looking after the children. Hazrat Shaikh (rahimahullah) said:
I was extremely grieved to learn that your wife left her salaah. All people have children, and all women attend to the domestic chores and responsibilities. Your wife is not the only person with children. Through missing the salaah, she has shown great ingratitude to Allah Ta‘ala for this favour (of children).
The gratitude and appreciation for being blessed with children is that one exerts oneself more in ibaadah and acts of worship. Inform your wife that after a person passes away, the very first thing regarding which they will be questioned about in the Hereafter will be their salaah. (Qutbul Aqtaab Hazrat Sheikhul Hadith Moulana Muhammad Zakariyya (rahmatullahi ‘alaih) pg. 428)
