Look at the wonders of the world surrounding you and you will feel Allah's might, today's sermon tells worshippers.
"You are advised to contemplate the revelations of Allah, the most exalted. Those who do so will realise the greatness of the Creator," says the sermon.
A verse from the Quran says: "Do you not see that Allah has subjected to you whatever is on the earth and the ships which run through the sea by his command?
"And he restrains the sky from falling upon the earth, unless by his permission. Indeed Allah, to the people, is kind and merciful."
Signs of Allah's existence and might are earthquakes, solar and lunar eclipses, and weather such as wind and rain.
"These are all great signs that human beings can see and feel in various times, reminding them of the weakness of man before the might of his Creator," the sermon continues.
The Prophet Mohammed advised Muslims on what they should do when they experienced such revelations.
For instance, when the wind blew he used to say: "O Allah, indeed, I ask you for its good, the good of what is in it, and the good of what it has been sent with.
"And I seek refuge in you from its evil. The evil of what is in it, and the evil of what it has been sent with."
During rainfall, he used to say: "O Allah, may it be a beneficial rain cloud."
If the rain was too heavy, he would say: "O Allah, send down rain in our suburbs but not on us."
The sermon encourages Muslims to reflect on Allah's existence in their daily lives.
