During these nights, one must strive his best to keep thinking about Allah (the Glorious, the Exalted), all along the night, and should not forget Him during any part of the night even for the sake of recommended and justified deeds. Also while offering prayer and supplications he should not think about any other thing even though if they happen to be recommended things.
For example, during prayer (salat), one should not think about recommended deeds like building of mosque, cleaning of mosque, and paying alms etc., because all these are indications of negligence; even during a part of the prayer (salat), he should not think about the next portion of the prayer, e.g. in the state of standing, to think about the prostration is negligence. He must try to concentrate upon whatever act of the prayer he is performing and should not be negligent about whatever he is doing or reciting. In order to make this task easier, before performing different acts of prayer, e.g. recital or genuflexion (rukoo), first of all, he should think about them briefly and then should perform them. And in case while performing a certain act, negligence dominates over him, and if a verse or invocation is recited with negligence, he must repeat it again.
For example, when he wants to stand towards Mecca (Qiblah) for prayer (salat) first of all, he should think briefly about the wisdom of standing towards Mecca, and then should turn his face in that direction; and when he wants to stand for the prayer, first of all, he should think about the meanings of standing, i.e., his standing is for truth and his resting upon his two feet is the indication of his hope (raj'a) and fear (khouf) about the acceptance of his worship. When he wants to recite the phrase:
"In the name of Allah the Beneficent, the Merciful."
First of all, he should think about its meaning in brief, and then should recite it with his tongue, and similar is the case with other acts of the prayer.
