Their senses of hearing...
Their senses of hearing, speech and sight are more powerful than those of ordinary people. Their physical organs are superior to those of ordinary people in their special qualities. Even the seeds in the loins or wombs heard the voice of Ibrahim (a.s) when he recited the Call (Azan) for Hajj. His eyes saw the kingdom of the heavens and the earth. Prophet Sulaiman (a.s) heard the conversation of the ant. In this way other prophets were endowed with special powers and qualities.
Each verse of the book of their existence is incomparable in its position. As for the descent of balance, it denotes their good moral behavior. The morals of all people would be judged in relation to them. The criterion of each thing is different. Material objects are weighed in a different kind of balance, and non-perceptible things are weighed differently. The balance of poetic meter is not an ordinary one, or the one used to weigh gold or silver; their weights are also completely different.
These weights are also not used in measuring temperature; a thermometer is required for this. In moral science also this criterion is useless. You will find a completely different standard there. In common parlance it is said: The habit of so and so is similar to the habit of so and so. He is like his father in moral qualities.
Thus we come to know that the morals of the prophets is that balance on which the morals of all the nations would be weighed on the Day of Judgment, and the morals of the people would be judged in accordance with the “best of morals” (of the Holy Prophet). Thus as far removed one is from the right path; the less would be the weight of his deeds. One who is nearer to this true measure would be rewarded most.
Allah says, “This weighing would be very accurate.” So that no one gets an opportunity to complain. “One who has done an iota of good or one who has done a little bit of evil” all would be accounted for. Actually this examination would be in relation to this “medium letter”. One who is nearest to it would have the heaviest pan of deeds, and the further away one is from the criterion, the lighter his deeds would become. Now consider how difficult this path is.
If it had been an easy way the divine saints would not have subjected themselves to severe penance and would not have forgone ease and comforts. Even those who are considered the patron saints of mysticism are found helpless and defeated at one time or the other.
