In these series of articles we focus on verses that are intended to say something about Imam Mahdi who is the Last Savior.
God in surah al-Nahl, verse 1 states, “Allahs commandment has come to pass, so do not haste for it. Allah is the Absolute Pure and far above having any partner as the polytheists attribute to Him.” «أَتىَ أَمْرُ اللَّهِ فَلَا تَسْتَعْجِلُوهُ سُبْحَانَهُ وَ تَعَالىَ عَمَّا يُشْرِكُونَ»
There is a narration form Imam Saadiq (the Shiite sixth Imam) explaining this verse,
عَنْ أَبِي عَبْدِ اللَّهِ ع فِي قَوْلِ اللَّهِ عَزَّ وَ جَلَّ أَتى أَمْرُ اللَّهِ فَلا تَسْتَعْجِلُوهُ قَالَ هُوَ أَمْرُنَا أَمْرُ اللَّهِ لَا يُسْتَعْجَلُ بِهِ يُؤَيِّدُهُ ثَلَاثَةُ أَجْنَادٍ الْمَلَائِكَةُ وَ الْمُؤْمِنُونَ وَ الرُّعْبُ
“The words of God saying ‘Allahs commandment has come to pass, so do not haste for it’ points to what is decreed for us and God ordained us not to haste for it (pointing to the time of Imam Mahdi’s appearance). (When our Upriser comes) God will assist him with three things: Angels, the believers and fear (the He will cast on the hearts of the disbelievers).”
This verse with the mentioned narration contains some considerable points:
1- The promise of God will certainly be fulfilled: A decision that is made has two stages: the first one is to decide for it and the second one is to implement it. When God decides for something it means that it has to be applied in the future. But when it is due to be implemented depends on the discretion of God and we should not haste nor desire to be delayed. The time of Appearance is one of the most important of these decisions that will take place in an exactly determined time. God is all-Wise and also His knowledge is comprehensive; hence, whatever He decides is the best decision although we may not understand it’s philosophy.
2- Imam Mahdi will be assisted with apparent and hidden forces: When the Imam comes all available forces will help him. The believing followers, angels and even fear; therefore, the adversaries will be fewer in power (since the believers along with angels are more powerful than them) and scared. Above all, God is the assistant of the Imam and his followers. The result is that the enemies can neither advance physically nor spiritually. The issue of Imam Mahdi’s advent and his victory over opponents is something that God has decided for and those who oppose are weaker than to afford to change it.
