Maintaining the ties of kinship is a way to enter Jannah
Abu Ayyub Khalid bin Zaid Al-Ansari (radi Allahu anhu) reported: A man came to the Messenger of Allah (sal Allahu alaihi wa sallam) and said, “Direct me to a deed which will admit me to Jannah and take me away from the Fire.” The Messenger of Allah (sal Allahu alaihi wa sallam) said, “Worship Allah and associate no partner with Him, perform As-Salat, pay Zakat, and maintain the ties of kinship.”
[Sahih al-Bukhari and Muslim]
This Hadith indicates the actions which constitute the means to attain Jannah and salvation from Hell. Thus, it makes evident that Jannah cannot be achieved by wishful thinking. One cannot get it without Faith and good deeds. In the absence of these two factors, intercession of any person will be of no avail.
And Allah Knows Best!
