Before going to bed, the Prophet, peace be upon him, used to say:

All praise is due to Allah, who fed us, gave us drink, satisfied us and provided us with shelter; for how many are there who have none to fill their needs for them or a provider of shelter. [Sahih Muslim]

Seeking Allah’s Protection– say three times in the morning and the evening:

In the name of Allaah with those name nothing is harmed on earth nor in the heavens and He is The All-Seeing, The All-Knowing. [Ahmad & Abdu Dawud, Sahih]

Another one of my favorites is the following one that is praising Allah in the highest form. It is among the first things to be said early in the morning (upon awaking) and before sleeping. It is narrated by Muslim, At-Tirmithi, Abu Dawud and Ibn Majah.

How perfect Allaah is and I praise Him by the number of His creation and by as much as His pleasure, and by the weight of His throne, and the ink of His words. (To be said three times)

This comes to us from the hadith about Umm AlMu’mineen, Juwairiyah, may Allah be pleased with her. That day she was sitting after Salatul Fajr in remembrance of Allah, when the Prophet, peace be upon him went out from her apartment. He returned much later that morning and she was still sitting there praising Allah. The Prophet, peace be upon him, asked her if she had been sitting there continuously doing that from the time he had left. When she replied in the affirmative, he told her that if she repeated 4 things three times, it would outweigh what she had been saying the whole time she had been sitting in praise of Allah. Subhaanallah! He gave her a superlative form of praising Allah. Let us make use of these powerful words and make them part of our routine.
