In the verse I have just recited the Almighty Allah (swt) states, “The mosques of Allah are only to be maintained by those who believe in Allah and the Last Day and establish prayer and give zakah and do not fear except Allah, for it is expected that those will be of the [rightly] guided.” 
In the hadith I have just read, the Prophet Muhammad (saw) says, “Whoever builds a mosque for the sake of Allah, Allah will build for him a house in Paradise.” 
Mosques, where we come together to submit our servitude to our Lord (swt) in this hour of Friday when prayers are accepted, are the houses of Allah and work of Muslims. Mosques provide cure for our souls depressed by loneliness and peace for our hearts tired in the busyness of life. Mosques are the heart of our residential areas, the spirit of our cities, and the safe haven for our noble nation and the Muslim ummah.
May His (swt) mercy be upon the deceased brothers and sisters of ours, from past to present, who have had a leading role in the construction and improvement of our mosques, as well as those who have provided support, aid, and service to them with the love of worship. May He (swt) grant those still alive a healthy and peaceful life.
