What is meant by glorifying and praising Allah before making supplication?

Glorifying and praising Allah before supplicating means to begin by thanking and expressing gratitude to Allah, mentioning His names and attributes, and acknowledging one's humility and dependence on Him, as a prelude to the supplication. The Prophet, peace be upon him, commanded to begin by glorifying and praising Allah, then sending prayers upon the Prophet, before making a supplication, as this increases the likelihood of the supplication being answered. An example of this is the supplication of the Prophet, peace be upon him, during his night vigil, where he would frequently praise and glorify Allah before beginning his supplication. Seeking intercession through Allah's names, attributes, and His servitude ensures, by Allah's will, the answering of supplication, as seen in Surat Al-Fatiha and the supplications of the Prophets.
