السلام عليكم ورحمة الله أحسن الله إليكم Ustadh what do you recommend me to advise a sibling who is struggling with salah and wants to rekindle their relationship with it. As now they feel like they are only praying for parents. Are there any books/durus on the topic? جزاك الله خيرا وبارك الله فيكم

Let them continue to pray to get into the habit of praying and it will grow on them. As for how to advise them, I think you know them better so u know what can affect them. I would recommend videos about its importance to be sent to them from time to time.
