Shaikh ul Islaam Ibn Taymiyyah (rahimahullaah) explained:
“Supplication is a reason that repels tribulation. So if it is stronger than it; then it repels it, yet if the reason for the tribulation is stronger then it does not repel it, however it lessens it and weakens it, and it is due to this that one has been commanded at the times of the eclipse and the (other) signs with: prayer and supplication and seeking forgiveness and giving charity and emancipation (of slaves), and Allaah Knows best.”
