My choice of Muhammad to lead the list of the world's most influential persons may surprise some readers and be questioned by others, but he was the only man in history who was supremely successful on both the religious and secular levels.
Continually seeking knowledge until death
True knowledge does not mean obtaining a degree or diploma that will let one earn an income and guarantee a good standard of living, after which one turns away from learning and does not explore the treasure of knowledge any further; true learning means that one continues to read and study, increasing one's learning day by day, following the words of the Quran. Allah (SWT) said: “But say, O my Lord! Advance me in knowledge.” (Qur’an 20:114)
Muslim reports from Ibn Mas'ud (RA) that the Prophet (SAAS) said: “No one who has even a weight of pride in his heart will enter Paradise.” A man asked him, “What if he likes his clothes and shoes to look good?” (Meaning, is this counted as pride?) The Prophet (SAAS) said: “Allah is beautiful and loves beauty. Pride means denying the truth and looking down on other people.”
