944. hadíth
وَ قَالَ أَمِيرُ اَلْمُؤْمِنِينَ عَلَيْهِ اَلسَّلاَمُ: "مَنْ رَضِيَ مِنَ اَلدُّنْيَا بِمَا يُجْزِيهِ كَانَ أَيْسَرُ اَلَّذِي فِيهَا يَكْفِيهِ وَ مَنْ لَمْ يَرْضَ مِنَ اَلدُّنْيَا بِمَا يُجْزِيهِ لَمْ يَكُنْ شَيْءٌ فِيهَا يَكْفِيهِ".
Commander of the Faithful Imam Ali ibn Abi Talib (a.s) said: "Whoever is content with what suffices him from this world, the least of what is in it will be enough for him. And whoever is not content with what suffices him from this world, nothing in it will ever be enough for him."
