True Piety

Al-Baqara (The Cow) 2:177

لَّيْسَ الْبِرَّ أَن تُوَلُّواْ وُجُوهَكُمْ قِبَلَ الْمَشْرِقِ وَالْمَغْرِبِ وَلَـكِنَّ الْبِرَّ مَنْ آمَنَ بِاللّهِ وَالْيَوْمِ الآخِرِ وَالْمَلآئِكَةِ وَالْكِتَابِ وَالنَّبِيِّينَ وَآتَى الْمَالَ عَلَى حُبِّهِ ذَوِي الْقُرْبَى وَالْيَتَامَى وَالْمَسَاكِينَ وَابْنَ السَّبِيلِ وَالسَّآئِلِينَ وَفِي الرِّقَابِ وَأَقَامَ الصَّلاةَ وَآتَى الزَّكَاةَ وَالْمُوفُونَ بِعَهْدِهِمْ إِذَا عَاهَدُواْ وَالصَّابِرِينَ فِي الْبَأْسَاء والضَّرَّاء وَحِينَ الْبَأْسِ أُولَـئِكَ الَّذِينَ صَدَقُوا وَأُولَـئِكَ هُمُ الْمُتَّقُونَ

True piety does not consist in turning your faces towards the east or the west - but truly pious is he who believes in God, and the Last Day; and the angels, and revelation, and the prophets; and spends his substance - however much he himself may cherish - it - upon his near of kin, and the orphans, and the needy, and the wayfarer, and the beggars, and for the freeing of human beings from bondage; [146] and is constant in prayer, and renders the purifying dues; and [truly pious are] they who keep their promises whenever they promise, and are patient in misfortune and hardship and in time of peril: it is they that have proved themselves true, and it is they, they who are conscious of God.

At-Tauba (The Repentance) 9:19

أَجَعَلْتُمْ سِقَايَةَ الْحَاجِّ وَعِمَارَةَ الْمَسْجِدِ الْحَرَامِ كَمَنْ آمَنَ بِاللّهِ وَالْيَوْمِ الآخِرِ وَجَاهَدَ فِي سَبِيلِ اللّهِ لاَ يَسْتَوُونَ عِندَ اللّهِ وَاللّهُ لاَ يَهْدِي الْقَوْمَ الظَّالِمِينَ

Do you, perchance, regard the [mere] giving of water to pilgrims and the tending of the Inviolable House of Worship as being equal to [the works of] one who believes in God and the Last Day and strives hard in God's cause? These [things] are not equal in the sight of God. And God does not grace with His guidance people who [deliberately] do wrong.
