Answer:
Allah Almighty says:
خُلِقَ الْإِنسَانُ مِنْ عَجَلٍ ۚ سَأُرِيكُمْ آيَاتِي فَلَا تَسْتَعْجِلُونِ ﴿٣٧﴾
Man was created very impatient; I will soon show you My signs, so do not demand hastily from Me.
In another place He says:
وَيَدْعُ الْإِنسَانُ بِالشَّرِّ دُعَاءَهُ بِالْخَيْرِ ۖ وَكَانَ الْإِنسَانُ عَجُولًا ﴿١١﴾
And man prays for evil as he prays for good, and man is ever hasty.
Imam Qurtubi, in his Tafsir خُلِقَ الْإِنسَانُ مِنْ عَجَلٍ, states that man is naturally prone to hastiness and is inherently impatient. Knowledge and insight require steadiness and contemplation, whereas hastiness is an obstacle to this. At the time of hastiness, Satan instills his evil in man from places he is not even aware of.
Sayyiduna Anas bin Malik (RA) narrates from the Prophet Muhammad (SAW) that he said:
التاني من الله، والله من الشيطان، وما من أحد أكثر معاذير من الله، وما من شيء أحب إلى الله من الحمد
Patience is from Allah, while hastiness is from Satan, and no excuse is accepted beyond Allah, and nothing is more beloved to Allah than praise (Hamd).
