58 Nawawi says in Rawdah at-Taalibeen (1/224 published by Maktab al-Islami):
"The intention is the purpose, so the person about to pray brings to mind that prayer
and what is relevant of its characteristics, such as which prayer it is, whether
it is obligatory etc. & he brings these things together in his intention with
the first takbeer."
59 Bukhaari, Muslim and others. It is given in Irwaa'
(no. 22)
