Counting the number of times one says Tasbih using the right hand

A: It is better to count the numbers of Tasbih with the right hand, but it is permissible to use the fingers of both hands too. There are Da‘if (weak) Hadith that mention the merits of reciting Surah Al-Kahf on Fridays. However, its recitation by some of the Companions of the Prophet (may Allah be pleased with them) is the evidence that it is Mustahab (desirable) to recite it on Fridays. In addition, it is Mustahab to recite Surah Al-Sajdah on Fridays in the Fajr (Dawn) Prayer together with Surah Al-Insan. There is no evidence of any special merit in the recitation of Surahs Yasin and Al-Rahman, or Al-Baqarah and Al-Ikhlas on Fridays. (Part No. 5; Page No. 424)  Furthermore, it is Mustahab to perform Sujud-ul-Tilawah when reciting an Ayah of Ayat-ul-Sujud, whether while offering Salah or not. This act is Mustahab for both the reciter and the listener, but not for someone who does not have the intention to listen.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
