Whenever the Prophet (may peace and blessings be upon him) would see anything that troubled him, he would pray. When it was windy, when it was dark, for anything and everything, he would turn to Allah. And we have his duas, and in particular, we have the Prayer of Need (Salat al Haja) So ask Allah for openings, to remove difficulties. The Prophet (may peace and blessings be upon him), if anything bothered him deeply, he would pray.
Shaykh Abdullah bin Bayyah, Session 10, Reviving the Islamic Spirit Convention, Dec 26th 2009.
