Events of life sometimes make it hard to make fair decisions. What is the Muslim’s solution in making decisions of life’s events?

Question

Istikhaarah (Prayer of decision-making), is a tool for a Muslim. Life is made of decisions. For some only notice the decisions when they have long-term consequences. Decisions of all kinds are there every moment. In making decision, big or small, we can only estimate its probable result. Based on our limited knowledge, we cannot predict the future. The Prophet (Sallallahu Alayhi Wasallam) used to teach the Companions (Radhiyallahu Anhum) to make Istikhaarah in every matter.
