أَلَهُمْ أَرْجُلٌۭ يَمْشُونَ بِهَآ ۖ أَمْ لَهُمْ أَيْدٍۢ يَبْطِشُونَ بِهَآ ۖ أَمْ لَهُمْ أَعْيُنٌۭ يُبْصِرُونَ بِهَآ ۖ أَمْ لَهُمْ ءَاذَانٌۭ يَسْمَعُونَ بِهَا ۗ قُلِ ٱدْعُوا۟ شُرَكَآءَكُمْ ثُمَّ كِيدُونِ فَلَا تُنظِرُونِ
Have they feet wherewith they walk, or have they hands wherewith they hold, or have they eyes wherewith they see, or have they ears wherewith they hear? Say: Call upon your (so-called) partners (of Allah), and then contrive against me, spare me not!
Surah Al-A'raaf(7:195)

Virtues and Merits of the Prophet (pbuh) and his Companions
Chapter: The signs of Prophethood in Islam
Narrated `Aisha:
Once Fatima came walking and her gait resembled the gait of the Prophet (ﷺ) . The Prophet (ﷺ) said, "Welcome, O my daughter!" Then he made her sit on his right or on his left side, and then he told her a secret and she started weeping. I asked her, "Why are you weeping?" He again told her a secret and she started laughing. I said, "I never saw happiness so near to sadness as I saw today." I asked her what the Prophet (ﷺ) had told her. She said, "I would never disclose the secret of Allah's Messenger (ﷺ)." When the Prophet (ﷺ) died, I asked her about it. She replied. "The Prophet (ﷺ) said: 'Every year Gabriel used to revise the Qur'an with me once only, but this year he has done so twice. I think this portends my death, and you will be the first of my family to follow me.' So I started weeping. Then he said. 'Don't you like to be the chief of all the ladies of Paradise or the chief of the believing women? So I laughed for that."
