A Hadith every day, with an explanation of a part of it.
السلام عليكم ورحمة الله وبركاته
عَنْ عَبْدِ اللهِ بْنِ عُمَرَ رَضِيَ اللهُ عَنْهُمَا، قَالَ: قَالَ رَسُولُ اللهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ:
بُنِيَ الْإِسْلَامُ عَلَى خَمْسٍ: شَهَادَةِ أَنْ لَا إِلَهَ إِلَّا اللهُ وَأَنَّ مُحَمَّدًا رَسُولُ اللهِ، وَإِقَامِ الصَّلَاةِ، وَإِيتَاءِ الزَّكَاةِ، وَحَجِّ الْبَيْتِ، وَصَوْمِ رَمَضَانَ.
(رواه البخاري ومسلم).
On the authority of Abdullah bin Umar (may Allah be pleased with them both), who said: The Messenger of Allah (peace and blessings of Allah be upon him) said:
"Islam is built upon five (pillars): testifying that there is no god but Allah and that Muhammad is the Messenger of Allah, establishing prayer, paying Zakat (obligatory charity), performing Hajj (pilgrimage) to the House (the Kaaba), and fasting in Ramadan." (Narrated by Al-Bukhari and Muslim)
The meaning of "Islam is built upon five" is that there are five acts through which the completeness of a person's Islam is realized. A Muslim must perform these five outward acts because they are the pillars of Islam. Through these pillars, one achieves the perfection of their faith. If a person misses any one of them despite being capable of performing it, then their Islam is incomplete.
