Title: Dua by Saeed al-Makki
Description: Call on your Lord with humility and in private: for Allah loveth not those who trespass beyond bounds.[Surah 7:55]
"Dua is the essence of Ibadah (worship)."
[at Tirmdhi, Ahmad]
"The dua of a Muslim for his brother (in Islam) in his absence is readily accepted, an angel is appointed to his side, whenever he makes a beneficial dua for his brother the appointed angel says "aameen and may you also be blessed with the same".
[Sahih Muslim]
