How sound is the Hadith: "Is anyone of you incapable of earning one thousand good deeds every day?" — the entire Hadith — and does the reward increase with an increase in Tasbeeh?

The aforementioned hadith is authentic, stating that whoever glorifies Allah one hundred times will have a thousand good deeds recorded for them, or a thousand sins forgiven. Imam al-Nawawi mentioned that the narrations in Muslim came with "or will be forgiven," while other narrations came with "and will be forgiven." A good deed is multiplied tenfold, so whoever glorifies Allah a thousand times will have ten thousand good deeds recorded for them. Whoever exceeds one hundred glorifications will be rewarded for the excess, multiplied. Other hadiths have been narrated concerning the virtue of multiplied remembrance (dhikr), such as the saying: "There is no god but Allah, alone, without partner. To Him belongs all sovereignty and praise, and He is over all things competent," one hundred times, and "Exalted is Allah above all imperfection, and by His praise," one hundred times. These hadiths indicate the virtue of whoever exceeds the mentioned number.
