Bismillahir'rahmannir'rahim.

Allahumma sali'ala sayyiddina Muhammadin wa 'ala alay sayyiddina Muhammadin wa barik wa salim.

"When a believer is stricken with any hardship, or pain, or anxiety, or sorrow, or harm, or distress - even if it be a thorn that has hurt him - Allah redeems thereby some of his failings*."
~Recorded in both Bukahri and Muslim

*failings [in case anyone did not understand] meaning sins.

Allahumma sali'ala sayyiddina Muhammadin wa 'ala alay sayyiddina Muhammadin wa barik wa salim. Rawdhina billahi Rabba wa bil'islaami deena wa bi'Muhammadin nabiyaa, wa akhirud'duana anil'hamdulillahi rabbil'alameen.

Bismillahir'rahmannir'rahim.

Allahumma sali'ala sayyiddina Muhammadin wa 'ala alay sayyiddina Muhammadin wa barik wa salim.

"The word "waliyy" is linguistically derived from "wala`", which means closeness and giving victory. A "waliyy" of Allah, then, is someone who draws close to Allah by performing everything that has been made obligatory for him. He is busied by Allah [from everything else] and his heart is drowned in direct experience of the light of Allah's majesty. Whenever he looks [at anything], he sees it as something that points to Allah's omnipotence; whenever he hears [anything], he hears it as something that reminds him of Allah; whenever he speaks, he speaks praises of Allah; whenever he moves, he moves to obey Allah; and whenever he exerts himself, he exerts himself in something that draws him closer to Allah. He never slackens in the remembrance of Allah, and his heart beholds none except Allah. This is a description of the "awliya'" of Allah. Whenever a servant of Allah fits this description, Allah is his friend, gives him victory, and helps him: Allah Most High says [in a verse in Surat al-Baqara], "Allah is the friend of those who believe.""
