Is There A Religious Basis For Reciting Kalimat Al-Tawhid For Seventy Thousand (70.000) Times?

Is there a religious basis for reciting kalimat al-tawhid for seventy thousand (70.000) times?

Lexical meaning of kalimat al-tawhid is “the sentence of expressing the oneness of Allah.” It consists of the sentence of “La ilaha illallah”, which means “There is no deity but Allah.” The meaning of this sentence constitutes the foundation of Islam. Prophet Muhammad (saw) said, “The one who will be the happiest person thanks to my intercession on the Day of Judgment is the one who recites La ilaha illallah sincerely.” (Bukhari, ‘Ilm, 33; Riqaq 51).

Dhikr means remembering and reminding. Reciting kalimat al-tawhid as dhikr is a rewarded deed as it will make those who recite and listen be reminded of Allah, it is the most beautiful dhikr. The Messenger of Allah (saw) said, “The most virtuous zikr is to recite ‘La ilaha illallah’ and the most virtuous dua is to recite ‘Alhamdulillah.’” (Ibn Majah, Adab, 44).

Besides, there are hadiths claiming that those who recite “La ilaha illallah” a hundred times a day are going to be rewarded in different ways (Ibn Majah, Adab, 54). It is not correct to believe and claim that the duas and the dhikrs should be made and recited in certain numbers, except those given in authentic hadiths.
