One Sunnah after labbaik
On Arrival at miqaat – On wearing ehram – after praying nafil – after making intention – after saying labbaik

Supplicating after saying labbaik is an act of sunnah as has been reported in holy hadith: أَنَّهُ كَانَ إِذَا فَرَغَ مِنْ تَلْبِيَّتِه سَأَلَ اللهَ رِضْوَانَهُ وَالْجَنَّةَ وَاسْتَعْفَاهُ بِرَحْمَتِه مِنَ النَّارِ
Translation: after completing the labbaik Rasulallah sallallaahu alaihi wasallam were asking from Allah the glorified His pleasure and were demanding Jannah seeking refuge from hell. (Musnad Imam shafi, Page 123) of course, Allah pak is pleased with our beloved master sallallaahu alaihi wasallam no doubt that he is a Jannati, bestowed by the devine master of paradise but all these supplications are for our understanding and guidance in order for us to ask supplications in the name of sunnah. Now the ehram just begins hence forth only labbaik becomes your recital and repetition – recite this while sitting, standing and moving around abundantly.
