A wise man was telling me this he asked me what would my answer be I was dumb founded. Story goes like this.
A very pious man was worshiping Allah in a cave , while he was busy worshiping Allah he saw a lizard walking on the cave wall to catch a fly which was sitting a little bit away.
Now his dilemma was if he saves the fly he will be questioned as to why did he not let one of Allah’s creation, the lizard take care of its hunger.
If he does not save the fly and let lizard eat it he will be questioned as to why did he not save Allah’s creation ,the fly , from becoming food for other creation.
This pious man had nothing to eat or drink any more as he was praying for a long period of time in that cave and had already consumed the last grain of food and has drank the last drop of water so he could not offer anything to lizard to satisfy its hunger.
