What are the etiquettes of supplication?

Question:
As for the etiquettes of supplication, what are the etiquettes of supplication, O Shaykh?

Answer:
The etiquettes of supplication are numerous. Among them is that one supplicates to Allah (Mighty and Majestic) with sincerity and does not supplicate to anyone else alongside Him; rather, he supplicates to none but Allah (Mighty and Majestic). Allah (Mighty and Majestic) said: This is among the greatest etiquettes of supplication. Another etiquette is that the servant acknowledges his weakness and his need for his Lord (Glorified and Exalted is He), and that he is not free from the need of Allah (Mighty and Majestic). Likewise, among the etiquettes of supplication is that one supplicates to Allah while being certain of the response, for supplication is not answered from a heedless, distracted heart, but rather one must be certain of the response when he supplicates to his Lord (Glorified and Exalted is He), for nothing is too difficult for Allah and nothing is too great for Him to grant.
