18:46 Wealth and children are [but] adornment of the worldly life. But the enduring good deeds are better to your Lord for reward and better for [one's] hope.

"Remember Me, and I shall remember you" (2:152)

Hadith: "Those that remember Me in their heart, I remember them in My heart; and those that remember Me in a gathering (i.e. that make mention of Me), I remember them (i.e. make mention of them) in a gathering better than theirs."

Hadith: When asked, "O Messenger of Allah, who are the single-hearted?" he replied, "The men and women who remember Allah abundantly."

Hadith: the Prophet (salAllahu alayhi wasalam) said, "Perform the enduring goods deeds (al-baaqiyaat al-SaliHaat) more frequently." They asked, "What are these enduring good deeds?" The Prophet replied: Takbir [Allahu Akbar], Tahlil [la ilaha illallah], Tasbih [Subhan'Allah], alhamdulillah, and la hawla wa la quwwata illa billah
سُبْحَانَ اللّهِ ، والْحَمْدُللّهِ ، وَ لا اِلهَ اِلَّا اللّهُ ، وَ اللّهُ اَكْبَرُ -

SubhanAllah, walHamdulilah,
wa La illaha ilAllahu, waAllahu Akbar

(Glory be to Allah, All Praise is for Allah, There is No God but Allah, Allah is the Greatest)

Hadith: the Prophet said: "When a servant of Allah utters the words la ilaha illallah (there is no God except Allah) sincerely, the doors of heaven open up for these words until they reach the Throne of Allah, so long as its utterer keeps away from the major sins.”[14]

لا اِلهَ اِلَّا اللّهُ - La illaha ilAllah(u) (There is No God But Allah)
Abu Huraira reported that the Prophet said, "Renew your faith." "How can we renew our faith?" they asked. The Prophet replied: "Say always: la ilaha illallah."[15]

Prophet Muhammad said: “For me to say (the above) is dearer to me and all that the sun rises upon (ie the whole world).”
Hadith: These are the Most beloved words to Allah subhana wa ta'ala. There is no harm in which ever one you start with.

Allahu Akbar
