Then there is a hadith
عَنْ عَائِشَةَ قَالَتْ قَالَ رَسُولُ اللَّهِ -صلى الله عليه وسلم- :« صَلاَةٌ بِسِوَاكٍ خَيْرٌ مِنْ سَبْعِينَ صَلاَةً بِغَيْرِ سِوَاكٍ
“One prayer with a Siwak is better than seventy prayers without a Siwak”[1]

The hadith is acceptable; as prayer with the Siwak

First 10 days of Dhul Hajj Part 2

Narrated Abu Sa’eed (radiyallaahu-anhu): I heard the Prophet (sallal-laahu-alayhi-wasallam) saying, ”Whoever observes Sawm (fast) for one day in Allaah’s Cause (to seek His good pleasure), Allaah will keep his face away from (hell) fire (a distance covered by a journey of ) seventy years”.

Reference
Each day in these 10 days, Allah rewards the Muslim who fasts as if they had fasted a whole year.

Reference

In the above article it says

"During this time, every good deed is rewarded 700 times."

Next there is a weak Hadith that states

‘A married person’s worship is seventy times more rewarding than an unmarried person’

Also in another narration
‘Two rakats of Salah performed by a married person is better than seventy rakats of an unmarried person’

It is a weak Hadith but then when I came across this article

It made me think, maybe the hadith is true.

And as we know
Abu Huraira reported: The Messenger of Allah, peace and blessings be upon him, said, “The supplications of three persons are never turned away: a fasting person until he breaks his fast, a just ruler, and the supplication of the oppressed which is raised by Allah above the clouds, the gates of heaven are opened for it, and the Lord says: By my might, I will help you in due time.”
