Anas ibn Malik reported: The Messenger of Allah, peace and blessings be upon him, was never asked anything for the sake of Islam but that he would give it. A man came to the Prophet and he gave him many sheep, so the man returned to his people and he said, “O my people! Embrace Islam, for Muhammad gives in charity as if he has no fear of poverty!”
In another narration, Anas said, “Indeed, a man would embrace Islam desiring worldly gains. He would not practice Islam but for a while, until Islam became more beloved to him than the world and everything in it.”

عَنْ أَنَسٍ قَالَ مَا سُئِلَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَلَى الْإِسْلَامِ شَيْئًا إِلَّا أَعْطَاهُ قَالَ فَجَاءَهُ رَجُلٌ فَأَعْطَاهُ غَنَمًا بَيْنَ جَبَلَيْنِ فَرَجَعَ إِلَى قَوْمِهِ فَقَالَ يَا قَوْمِ أَسْلِمُوا فَإِنَّ مُحَمَّدًا يُعْطِي عَطَاءً لَا يَخْشَى الْفَاقَةَ
وفي رواية أخرى قال إِنْ كَانَ الرَّجُلُ لَيُسْلِمُ مَا يُرِيدُ إِلَّا الدُّنْيَا فَمَا يُسْلِمُ حَتَّى يَكُونَ الْإِسْلَامُ أَحَبَّ إِلَيْهِ مِنْ الدُّنْيَا وَمَا عَلَيْهَا
