What is a reliable website for obtaining the supplications and remembrances (Duas and Athkar) of the the Prophet (peace be upon him) in order to print a free booklet, and will the one who does so be rewarded?

There are many books of remembrances (dhikr) and supplications (du'a), and among the best of them are Imam An-Nawawi's "Kitab Al-Adhkar" and "Hisn Al-Muslim." You can print one or both of them, or compile authentic supplications and remembrances from them or from other reliable books, and distribute them among Muslims to earn a great reward. There is no known specialized website in this field.
