prophet Muhammad may Allah blessings be upon him and grant him peace said:-
مَنْ صَلَّى عَلَيَّ وَاحِدَةً، صَلَّى الله عَلَيْهِ عَشْرًا
Whoever prays on me once, may Allah bless him times ten.
It is the praise of Almighty Allah upon the servant in the highest ten times whenever a servant prays on his Prophet, by saying : may Allah blessings be upon him and grant him peace once.
He also said may Allah blessings and peace be upon him:-
إن من أفضل أيامكم يوم الجُمُعة، فيه خُلِقَ آدَمُ، وفيه الصَّعقة؛ فأكثِرُوا عليَّ من الصلاة فيه، فإن صلاتَكم معروضةٌ عليَّ.
One of your best days is Friday, when Adam was created, and by the thunderbolt"End of time". Do more for me by praying, for your prayer is offered to me.
He said:-
Almighty Allah astray those"people" before our time, jews choose Saturday, and Christian choose Sunday, Allah brought to us, he guide us through Friday, Bounty of Allah on Friday over a Saturday and Sunday
and exactly for those who are coming after our time till the day of Yahm Al-Qiyamah.
We are the last of the people of the world, and we are the first on the Day of Resurrection "yahm Al-Qiyamah" The judgment for them before any creatures.
May Almighty Allah blessings and peace be upon him.
