Narrated 'Abdullah bin Malik: Ibn Buhaina, "When the Prophet ﷺ prayed, he used to separate his arms from his body so widely that the whiteness of his armpits was visible".
The hadith also teaches us about the importance of following the Sunnah of our beloved Prophet ﷺ in all aspects of life, including prayer. By following in His footsteps, we can strive towards becoming better Muslims and increase our faith in Allah SWT. Furthermore, this hadith serves as an example for us on how we should conduct ourselves during prayer; with humility and respect towards Allah SWT at all times.
