فَتَعَالَى اللَّهُ الْمَلِكُ الْحَقُّ ۗ وَلَا تَعْجَلْ بِالْقُرْآنِ مِن قَبْلِ أَن يُقْضَىٰ إِلَيْكَ وَحْيُهُ ۖ وَقُل رَّبِّ زِدْنِي عِلْمًا

A dayee should have two major aims: to bring about a psychological revolution in his addressees so that they may become God-fearing or at least he should be able to raise questions in his hearers about his call. During the Dawah campaign in Makkah, the addressees were raising all sorts of questions, creating problems for the Prophet. The Prophet naturally wanted that the intervals between the revelations could be reduced, so that he could receive God’s guidance more frequently. This would have enabled him to deal more promptly and effectively with the questions and problems which arose daily during his dawah work in Makkah. He was told that the process of revelation was in accordance with a divine, pre-ordained plan. It would continue as the occasion warranted, and would reach its completion in due course. He was asked not to desire the revelation of future parts of the Quran before their divinely appointed time. However, he was advised to pray to God to increase his understanding of the vast wisdom enshrined in the verses of the Quran. Instead of wishing for an early revelation of Quranic verses, he was expected to have the desire to understand the reason for their being revealed gradually, on a pre-planned scale of priority.
