إِنَّمَا الأَعمَالُ بِالنِّيَّاتِ، وَإِنَّمَا لِكُلِّ امرِئٍ مَا نَوَى

Actions are (judged) by intentions, and every person will receive what they intended.

This is the first hadith in Sahih al-Bukhari — considered by many scholars to be the most important hadith in all of Islam.

بُنِيَ الإِسلاَمُ عَلَى خَمسٍ: شَهَادَةِ أَن لاَّ إِلَهَ إِلاَّ اللَّهُ وَأَنَّ مُحَمَّدًا رَسُولُ اللَّهِ، وَإِقَامِ الصَّلاَةِ، وَإِيتَاءِ الزَّكَاةِ، وَالحَجِّ، وَصَوْمِ رَمَضَانَ

Islam is built on five (pillars): the testimony that there is no deity except Allah and that Muhammad is His Messenger, establishing prayer, giving Zakat, performing Hajj, and fasting Ramadan.

One of the most frequently cited hadith — forms the structural foundation of Islamic practice.

الطَّهُورُ شَطرُ الإِيمَانِ

تَبَسُّمُكَ فِي وَجهِ أَخِيكَ لَكَ صَدَقَةٌ

لاَ ضَرَرَ وَلاَ ضِرَارَ

There should be no harming (oneself) and no harming (others).

Note on grading: the chain through Ibn Abbas is Hasan; the chain through Abu Sa'id al-Khudri is also Hasan. Together they mutually strengthen each other to Hasan li-ghayrihi. Some earlier scholars (e.g., Ibn al-Sakan) considered it Sahih due to combined chains.

لاَ يُؤمِنُ أَحَدُكُم حَتَّى يُحِبَّ لأَخِيهِ مَا يُحِبُّ لِنَفسِهِ
