A da‘eef hadith about the virtue of sending blessings upon the Prophet (blessings and peace of Allah be upon him)
Question

                i just wanted to know if this hadith is sahih or weak hadith

Imam Ahmad recorded from Abu Hurayrah that the Prophet said:
صَلُّوا عَلَيَّ، فَإِنَّهَا زَكَاةٌ لَكُمْ، وَسَلُوا اللهَ لِيَ الْوَسِيلَةَ، فَإِنَّهَا دَرَجَةٌ فِي أَعْلَى الْجَنَّةِ، لَا يَنَالُهَا إِلَّا رَجُلٌ، وَأَرْجُو أَنْ أَكُونَ أَنَا هُو

(Send Salah upon me, for this is Zakah for you, and ask Allah to grant me Al-Wasilah, for it is a position in the highest part of Paradise which only one man will attain, and I hope that I will be the one.) This was recorded only by Ahmad.
Praise be to Allah.
	
	Muslim (384) narrated from ‘Abdullah ibn ‘Amr ibn al-‘Aas 
	that he heard the Prophet (blessings and peace of Allah be upon him) say: 
	“When you hear the muezzin, say what he says, then send blessings upon me, 
	for whoever sends blessings upon me, Allah will send blessings upon him 
	tenfold. Then ask Allah to grant me al-waseelah, for it is a station in 
	Paradise which only one of the slaves of Allah will attain, and I hope that 
	I will be the one. Whoever asks for al-waseelah for me, intercession will be 
	permissible for him.”

	
	It was narrated by Imam Ahmad in al-Musnad (8770), Ibn 
	Abi Shaybah in al-Musannaf (31784), al-Jahdami in Fadl as-Salaah 
	(46), Abu Ya ‘la in his Musnad (6414), and Ibn Raahawayh in his 
	Musnad (297), via :Layth, from Ka‘b, from Abu Hurayrah, that the Prophet 
	(blessings and peace of Allah be upon him) said: “Send blessings upon me, 
	for that is a means of purification for you. And ask Allah to grant me al-waseelah, 
	for it is a status in the highest part of Paradise, which no one will attain 
	except one man, and I hope that I will be him.”

	
	This is a da‘eef isnaad; Layth is ibn Abi Sulaym, who is 
	da‘eef and confused when narrating hadith. He was classed as da‘eef by 
	Ahmad, Ibn Ma‘een, an-Nasaa’i, Ibn Hibban and others.

	
	See: Mizaan al-I‘tidaal (3/420)

	
	Ibn Katheer said in his Tafseer (6/413):

	
	Its isnaad includes some narrators who were cricised.

	
	It was also classed as da‘eef by al-Albaani in Tahqeeq 
	Fadl as-Salaah li’l-Jahdami, and by the commentators on al-Musnad.

	
	The meaning of the hadith is sound in general terms, but this 
	version is da‘eef in its isnaad.

	
	There are many sound hadiths which speak of the virtue of 
	sending blessings upon the Prophet (blessings and peace of Allah be upon 
	him). See the answers to questions no. 2036,
	180852 and 128455.

	
	And Allah knows best.
