Your phone can wait one minute. Hearts find rest in the remembrance of Allah, not in the next notification.
The salaam ends and the phone is in your hand before the rug is folded. One notification, then ten more, and the quiet minute is gone.
Allah (SWT) tells us where the heart finds rest:
أَلَا بِذِكْرِ اللَّهِ تَطْمَئِنُّ الْقُلُوبُ
"Verily, in the remembrance of Allah do hearts find rest." (Surah Ar-Ra'd 13:28)
What Does Not Concern You
The Prophet ﷺ said: "Part of the excellence of a person's Islam is leaving what does not concern him." (Sunan at-Tirmidhi) A scroll that can wait for sixty seconds is exactly that.
Take Home
Put your phone face down, or in another room, before you pray. After the salaam, leave it alone for one full minute. Sit, remember Allah (SWT), then pick it up.
