,السلام عليكم ورحمة الله ,أحسن الله إليكم Ustadh please could you kindly give me some advice regarding qiyam al-layl. I used to establish it in the past regularly with a decent length, but for quite some time now I have not been able to, maybe due to my sins. جزاكم الله خيرا وبارك الله فيكم

You are right, sin is playing to this. This is a wake-up call. Another thing is, as the ulema say, always start with baby steps. Start with two rak'as and then you can increase bit by bit so that you can develop the habit like this and it doesn't feel overwhelming.
