Stay a little longer on the prayer mat. Those quiet moments after salaam are part of the prayer itself.
You finish the salaam and your hand is already reaching for your phone.
Stay a little longer. The Prophet ﷺ taught that the angels keep asking Allah on behalf of the one who remains where he prayed:
اللَّهُمَّ اغْفِرْ لَهُ، اللَّهُمَّ ارْحَمْهُ
"O Allah, forgive him. O Allah, have mercy on him." (Sahih al-Bukhari)
Those quiet minutes are not idle time. They are part of the prayer.
Take Home
After your next salah, stay seated for 30 seconds. Say SubhanAllah, Alhamdulillah, Allahu Akbar, then breathe. Build up to one minute.
