Is it considered an innovation (bid‘ah) to designate specific numbers for seeking forgiveness (istighfar) and sending blessings upon the Prophet (peace be upon him) as a punishment for missing acts of obedience or committing sins? And what is the alternative if that is the case?

"An-Nafs al-Lawwamah" (the self-reproaching soul) is that which blames its owner for shortcomings or for committing forbidden acts. Many of the early Muslims (Salaf) used to reproach themselves and discipline their souls through worship and obedience, without violating the Sharia or burdening the soul beyond its capacity. Examples of this include: 'Umar ibn al-Khattab's charity, fasting, prayers, and emancipation of slaves after his review with the Prophet, peace be upon him, regarding the Treaty of Hudaybiyyah; Aisha's emancipation of forty slaves after vowing not to speak to Ibn Az-Zubayr; Ibn 'Umar's staying up at night in prayer if he missed congregational prayer; Ibn Abi Rabi'ah's emancipation of a slave for missing the two Rak'ahs of the Fajr sunnah prayer; Ibn Wahb's fasting and giving charity after backbiting; and Ibn 'Awn's emancipation of two slaves for raising his voice above his mother's. It is not appropriate to specify a certain number for remembrance (dhikr) or worship continuously; rather, one should frequently remember Allah, seek forgiveness, and send blessings upon the Prophet, peace be upon him, in all circumstances.
