he (خَاتَمُ النَّبِيِّينَ صَلَّى اللّٰهُ عَلَيْهِ وَعَلٰى آلِهِ وَأَصْحَابِهِ وَسَلَّمَ) used to retire with food and water and spend days and weeks in remembrance of Allah.
5. The period of waiting had come to a close. His heart was overflowing with profound compassion for humanity. He (خَاتَمُ النَّبِيِّينَ صَلَّى اللّٰهُ عَلَيْهِ وَعَلٰى آلِهِ وَأَصْحَابِهِ وَسَلَّمَ) had a pressing urge to eradicate wrong beliefs, social evils, cruelty and injustice. The moment had arrived when he (خَاتَمُ النَّبِيِّينَ صَلَّى اللّٰهُ عَلَيْهِ وَعَلٰى آلِهِ وَأَصْحَابِهِ وَسَلَّمَ) was to be bestowed with 'Nabuwat'. One day, when he (خَاتَمُ النَّبِيِّينَ صَلَّى اللّٰهُ عَلَيْهِ وَعَلٰى آلِهِ وَأَصْحَابِهِ وَسَلَّمَ) was in the cave of Hira, Hazrat Jibril (Gabriel) (عَلَيْهِ ٱلسَّلَامُ) came and conveyed to him (خَاتَمُ النَّبِيِّينَ صَلَّى اللّٰهُ عَلَيْهِ وَعَلٰى آلِهِ وَأَصْحَابِهِ وَسَلَّمَ) the following message of Allah:
اقْرَأْ بِاسْمِ رَبِّكَ الَّذِي خَلَقَ خَلَقَ الْإِنْسَانَ مِنْ عَلَقٍ اقْرَأْ وَرَبُّكَ الْأَكْرَمُ الَّذِي عَلَّمَ بِالْقَلَمِ
Read in the name of thy Lord Who created, created man from a clot (of congealed blood): Read and thy Lord is the Most Bountiful, Who taught (the use of) the pen, taught man that which he knew not. (Quran, 96:1-5)
