Renewal of Bayyat Everyday:
It is recommended that the mentioned Bayyat should be renewed everyday according to the evidence that Sayyid Ali Ibne Tawoos has mentioned in Misbahuz Zaer and other scholars have also mentioned in their books that among the recommended things is to recite the following Dua everyday after the Morning Prayer:
O Allah, convey to the master, the Master of the Time, from all the believer men and women in the easts of the earth and its west. In its lands and its seas, in its plains and its mountains, their living and their dead, and from my parents and my children and from me, from the blessings and greetings, which are the weight of Allah’s throne and ink on his words, and whatever His knowledge enumerates and his book encompasses. O Allah renew for him my covenant, pledge and allegiance on my neck on this day and whatever days (of my life) I live. O Allah, like You honored me with this honor, and gave me this excellence and bestowed this bounty to me especially, bless my master and chief, the leader of the time and make me from his helpers and followers and protectors and make me of those who seek martyrdom in his presence, with full eagerness, without any hesitation put me in that row of the army of those whom You have described in Your Book and said: “in ranks as if they were a firm and compact wall” on Your obedience and the obedience of Your Messenger and his progeny, peace be on them. O Allah, indeed, this allegiance is upon my neck till Judgment Day.
اَللَّهُمَّ بَلِّغْ مَوْلاَيَ صَاحِبَ الزَّمَانِ صَلَوَاتُ اللَّهِ عَلَيْهِ عَنْ جَمِيعِ الْمُؤْمِنِينَ وَ الْمُؤْمِنَاتِ
ُاللَّهُمَّ (إِنِّي) أُجَدِّدُ لَهُ فِي هَذَا الْيَوْمِ وَ فِي كُلِّ يَوْمٍ عَهْداً وَ عَقْداً وَ بَيْعَةً فِي رَقَبَتِي
اللَّهُمَّ كَمَا شَرَّفْتَنِي بِهَذَا التَّشْرِيفِ وَ فَضَّلْتَنِي بِهَذِهِ الْفَضِيلَةِ وَ خَصَصْتَنِي بِهَذِهِ النِّعْمَةِ
اللَّهُمَّ هَذِهِ بَيْعَةٌ لَهُ فِي عُنُقِي إِلَى يَوْمِ الْقِيَامَة
