Ibn Mas’ud reported: The Messenger of Allah, peace and blessings be upon him, said:
لَا يَدْخُلُ الْجَنَّةَ مَنْ كَانَ فِي قَلْبِهِ مِثْقَالُ ذَرَّةٍ مِنْ كِبْرٍ
No one who has the weight of a seed of arrogance in his heart will enter Paradise.
Someone said, “But a man loves to have beautiful clothes and shoes.” The Prophet said:
إِنَّ اللَّهَ جَمِيلٌ يُحِبُّ الْجَمَالَ الْكِبْرُ بَطَرُ الْحَقِّ وَغَمْطُ النَّاسِ
Verily, Allah is beautiful and He loves beauty. Arrogance means rejecting the truth and looking down on people.
