virtures of Surah Yaseen; and the permissiblity of zikr and reciting Darood

In trying to seek additional knowledge in my deen I often look at lectures on Youtube from various Scholars. Please find hereunder a link from one of the lectures with regards to the recitation of Surah Yaseen to derive certain benefits. Can you kindly advice me if this is authentic as many muslims including myself have been taught like the brother said to recite Surah Yaseen for various reasons and if this should not be done I would like to know please.
Also can you tell me the daleel in reciting Allah’s names a certain number of times again to derive certain benefits like saying Ya Wahab 1000 times for whatever needs you may have as Wahab means Bestower and other such names for different things.
In addition what is the daleel for reciting darood for certain benefits say like a 1000 times for increase in baraka.

Wa Alaikum As Salaam,
Sura Yaseen is a very blessed Sura which has many virtues and benefits in it. Some of these are:-
1) Maqal bin Yasar (RA) narrates that the Prophet (SAS) said, ‘Sura Yaseen is the heart of the Quran. Whoever recites it for the sake of Allah and for goodness in the hereafter, then he will be forgiven. Recite it upon your deceased ones’. (Recorded by Nasai, Abu Dawood, Ibn Hibban who says it is Saheeh (Sound). Recorded also by Ahmad and Hakim who says it is Saheeh (Sound).
2) In the Hadith of Anas (RA), it is recorded that whoever recites it (Surah Yaseen) one time, it is like reciting the Quran ten times’. (Recorded by Tirmizi).
3) In the Hadeeth of Jundub (RA), it is narrated that whoever recites it at night, seeking Allah’s pleasure, then he will be forgiven’. (Recorded by Ibn Hibban and Ibn Sunni).
4) Abu Darda (RA) narrates that whoever recites Sura Yaseen close to a dying person, then his death will be an easy one. (Recorded by Ad-Dailami and Ibn Hibban)
5) Abdullah bin Zubair (RA) narrates that whoever recites Surah Yaseen for any specific need, then it shall be fulfilled’. (Tafseer Al Mazhari).
6) It is narrated in the tradition of Harith bin Abu Umama that whoever recites Surah Yaseen, then if he is in fear, he will gain peace and safety. If he is sick, he will be cured. If he is starved, Allah will nourish him’. (Ad-Daa’i wad Dawaa).
7) In the narration of Ata (RA), it is reported that the Prophet (SAS) said, ‘whoever recites Sura Yaseen at the beginning of the day, then he will be in ease and goodness until the evening. And whoever recites it in the evening, the he will be in ease and goodness until the next morning’. (Recorded by Ad Darimi with a Sound Sanad).

With respect to reciting Allah’s names to invoke His blessings and assistance, this is permissible. However, reciting a specific name for a fixed number of times (as you have mentioned) is not evident in traditions (according to what we have read). Nevertheless, they are not empty of blessings and good results. It is possible that such practices can be from among the experiences of pious scholars of the past. In a similar manner, there are many benefits in reciting different daroods which are recorded in authentic books. However, doing it in a manner which you have described, is not evident from the traditions (according to our knowledge).

And Allah knows best,
Mufti Waseem Khan
