May Allah bless you.
When one finishes the tashahhud and duas in sitting position and coming to an end in salah does one need to make the intention to exit the salah or just say Tasleem ?
The Messenger of Allah peace be upon him said:
مِفْتَاحُ الصَّلاَةِ الطُّهُورُ وَتَحْرِيمُهَا التَّكْبِيرُ وَتَحْلِيلُهَا التَّسْلِيمُ
The key to prayer is purification, its opening is to say ‘Allahu Akbar’ and its closing is to make tasleem (saying As-salamu ‘alaikum wa rahmatullah).
So we end prayers by tasleem (tasleem includes the intention).
